Especially for 2D materials, the atomic electric fields influence the optoelectronic properties. In this study, the atomic‐scale electric field and charge density distribution of WSe<jats:sub>2</jats:sub> bi‐ and trilayers are revealed using an emerging microscopy technique, differential phase contrast (DPC) imaging in scanning transmission electron microscopy (STEM). For pristine material, a higher positive charge density located at the selenium atomic columns compared to the tungsten atomic columns is obtained and tentatively explained by a coherent scattering effect. Furthermore, the change in the electric field distribution induced by a missing selenium atomic column is investigated. A characteristic electric field distribution in the vicinity of the defect with locally reduced magnitudes compared to the pristine lattice is observed. This effect is accompanied by a considerable inward relaxation of the surrounding lattice, which according to first principles DFT calculation is fully compatible with a missing column of Se atoms. This shows that DPC imaging, as an electric field sensitive technique, provides additional and remarkable information to the otherwise only structural analysis obtained with conventional STEM imaging.</jats:p>","lang":"eng"}],"status":"public","publication":"Small","type":"journal_article","article_type":"original","language":[{"iso":"eng"}],"_id":"54868","project":[{"name":"TRR 142: TRR 142 - Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen","_id":"53"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"_id":"166","name":"TRR 142 - A11: TRR 142 - Subproject A11"},{"_id":"168","name":"TRR 142 - B07: TRR 142 - Polaronen-Einfluss auf die optischen Eigenschaften von Lithiumniobat (B07*)"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"department":[{"_id":"15"},{"_id":"170"},{"_id":"295"},{"_id":"790"},{"_id":"642"},{"_id":"286"},{"_id":"429"},{"_id":"230"},{"_id":"27"},{"_id":"35"},{"_id":"169"}],"user_id":"16199"},{"publication":"Climate Protection, Resource Efficiency, and Sustainable Mobility - Transdisciplinary Approaches to Design and Manufacturing Technology","type":"book_chapter","status":"public","department":[{"_id":"286"}],"user_id":"77496","_id":"47133","language":[{"iso":"eng"}],"publication_identifier":{"isbn":["978-3-8376-6377-8"]},"publication_status":"published","page":"61-86","citation":{"ama":"Bürger J, Lindner JKN.

However, improvement of their catalytic performance to the same level as state-of-the-art noble metal catalysts requires an in depth understanding of their working principle on an atomic level. As a contribution to this aim, a series of iron oxide catalysts with varying Fe loadings from 1 to 20 wt% immobilized on a γ-Al2O3 support is presented here, and a multidimensional structure–activity correlation is established. The CO oxidation activity is correlated to structural details obtained by various spectroscopic, diffraction, and microscopic methods, such as PXRD, PDF analysis, DRUVS, Mössbauer spectroscopy, STEM-EDX, and XAS. Low Fe loadings lead to less agglomerated but high percentual amounts of isolated, tetrahedrally coordinated iron oxide species, while the absolute amount of isolated species reaches its maximum at high Fe loadings. Consequently, the highest CO oxidation activity in terms of turnover frequencies can be correlated to small, finely dispersed iron oxide species with a large amount of tetrahedrally oxygen coordinated iron sites, while the overall amount of isolated iron oxide species correlates with a lower light-off temperature.","lang":"eng"}],"publication":"Catalysts"},{"publication_identifier":{"issn":["0377-0486","1097-4555"]},"publication_status":"published","page":"1237-1245","citation":{"apa":"Knust, S., Ruhm, L., Kuhlmann, A., Meinderink, D., Bürger, J., Lindner, J.

The replicated patterns can, however, only be as precise as their templates. Thus, the investigation of the morphology of polymer domains is of great importance. Commonly used analytical techniques (neutron scattering, scanning force microscopy) either lack spatial information or nanoscale resolution. Using advanced analytical (scanning) transmission electron microscopy ((S)TEM), we provide real space information on polymer domain morphology and interfaces between polystyrene (PS) and polymethylmethacrylate (PMMA) in cylinder- and lamellae-forming BCPs at highest resolution. This allows us to correlate the internal structure of polymer domains with line edge roughnesses, interface widths and domain sizes. STEM is employed for high-resolution imaging, electron energy loss spectroscopy and energy filtered TEM (EFTEM) spectroscopic imaging for material identification and EFTEM thickness mapping for visualisation of material densities at defects. The volume fraction of non-phase separated polymer species can be analysed by EFTEM. These methods give new insights into the morphology of polymer domains the exact knowledge of which will allow to improve pattern quality for nanolithography.</jats:p>"}],"publisher":"MDPI AG","date_created":"2022-11-15T14:20:33Z","title":"Characterisation of the PS-PMMA Interfaces in Microphase Separated Block Copolymer Thin Films by Analytical (S)TEM","issue":"1","year":"2020","_id":"34092","user_id":"77496","department":[{"_id":"15"},{"_id":"230"}],"article_number":"141","type":"journal_article","status":"public","date_updated":"2023-01-10T12:11:57Z","author":[{"first_name":"Julius","full_name":"Bürger, Julius","id":"46952","last_name":"Bürger"},{"full_name":"Kunnathully, Vinay","last_name":"Kunnathully","first_name":"Vinay"},{"last_name":"Kool","full_name":"Kool, Daniel","id":"44586","first_name":"Daniel"},{"first_name":"Jörg","last_name":"Lindner","full_name":"Lindner, Jörg","id":"20797"},{"full_name":"Brassat, Katharina","id":"11305","last_name":"Brassat","first_name":"Katharina"}],"volume":10,"doi":"10.3390/nano10010141","publication_status":"published","publication_identifier":{"issn":["2079-4991"]},"citation":{"chicago":"Bürger, Julius, Vinay Kunnathully, Daniel Kool, Jörg Lindner, and Katharina Brassat. “Characterisation of the PS-PMMA Interfaces in Microphase Separated Block Copolymer Thin Films by Analytical (S)TEM.” <i>Nanomaterials</i> 10, no. 1 (2020). <a href=\"https://doi.org/10.3390/nano10010141\">https://doi.org/10.3390/nano10010141</a>.","ieee":"J.

Here, we investigate the adsorption of DNA origami nanostructures in\r\nnanohole arrays which represent an important class of biosensors and may benefit from the\r\nincorporation of DNA origami-based molecular probes. Nanoholes with well-defined diameter\r\nthat enable the adsorption of single DNA origami triangles are fabricated in Au films on Siwafers by nanosphere lithography. The efficiency of directed DNA origami adsorption on the\r\nexposed SiO2 areas at the bottoms of the nanoholes is evaluated in dependence of various\r\nparameters, i.e., Mg2+ and DNA origami concentrations, buffer strength, adsorption time, and\r\nnanohole diameter. We observe that the buffer strength has a surprisingly strong effect on DNA\r\norigami adsorption in the nanoholes and that multiple DNA origami triangles with 120 nm edge\r\nlength can adsorb in nanoholes as small as 120 nm in diameter. We attribute the latter\r\nobservation to the low lateral mobility of once adsorbed DNA origami on the SiO2 surface, in\r\ncombination with parasitic adsorption to the Au film. While parasitic adsorption can be\r\nsuppressed by modifying the Au film with a hydrophobic self-assembled monolayer, the limited\r\nsurface mobility of the adsorbed DNA origami still leads to poor localization accuracy in the\r\nnanoholes and results in many DNA origami crossing the boundary to the Au film even under\r\noptimized conditions. We discuss possible ways to minimize this effect by varying the\r\ncomposition of the adsorption buffer, employing different fabrication conditions, or using other\r\nsubstrate materials for nanohole array fabrication."}]},{"status":"public","publication":"Langmuir","type":"journal_article","language":[{"iso":"eng"}],"department":[{"_id":"302"},{"_id":"286"}],"user_id":"48864","_id":"22664","intvolume":"        34","page":"14757-14765","citation":{"short":"K.

Two bottom-up techniques suitable for the formation of regular nanopatterns on\r\ndifferent length scales are nanosphere lithography (NSL) and block copolymer (BCP) lithography. In this\r\npaper it is shown that NSL and BCP lithography can be combined to easily design hierarchically nanopatterned\r\nsurfaces of different materials. Nanosphere lithography is used for the pre-patterning of\r\nsurfaces with antidots, i.e. hexagonally arranged cylindrical holes in thin films of Au, Pt and TiO2 on SiO2,\r\nproviding a periodic chemical and topographical contrast on the surface suitable for templating in subsequent\r\nBCP lithography. PS-b-PMMA BCP is used in the second self-assembly step to form hexagonally\r\narranged nanopores with sub-20 nm diameter within the antidots upon microphase separation. To\r\nachieve this the microphase separation of BCP on planar surfaces is studied, too, and it is demonstrated\r\nfor the first time that vertical BCP nanopores can be formed on TiO2, Au and Pt films without using any\r\nneutralization layers. To explain this the influence of surface energy, polarity and roughness on the microphase\r\nseparation is investigated and discussed along with the wetting state of BCP on NSL-pre-patterned\r\nsurfaces. The presented novel route for the creation of advanced hierarchical nanopatterns is easily applicable\r\non large-area surfaces of different materials. This flexibility makes it suitable for a broad range of\r\napplications, from the morphological design of biocompatible surfaces for life science to complex\r\npre-patterns for nanoparticle placement in semiconductor technology.","lang":"eng"}],"author":[{"first_name":"Katharina","full_name":"Brassat, Katharina","id":"11305","last_name":"Brassat"},{"first_name":"Daniel","last_name":"Kool","id":"44586","full_name":"Kool, Daniel"},{"first_name":"Julius","id":"46952","full_name":"Bürger, Julius","last_name":"Bürger"},{"id":"20797","full_name":"Lindner, Jörg","last_name":"Lindner","first_name":"Jörg"}],"volume":10,"date_updated":"2022-01-06T06:59:55Z","doi":"10.1039/c8nr01397g","publication_status":"published","publication_identifier":{"issn":["2040-3364","2040-3372"]},"has_accepted_license":"1","citation":{"ama":"Brassat K, Kool D, Bürger J, Lindner J.

For these areas of applications a high degree of integration in optical systems is much sought-after. In the context of diffraction gratings this means that the angle of diffraction should be rather high, which typically poses a problem as the fabrication of small grating periods is challenging. In this paper, we propose the use of nanosphere lithography (NSL) for the fabrication of two-dimensionally\r\nstructured electrodes with a periodicity of a few micrometers. NSL is based on the self-assembly of micro- or nanometer sized spheres into monolayers. It allows for easy substrate structuring on wafer scale. The manufactured electrode is combined with a liquid crystalline polymer-stabilized blue phase, which facilitates sub-millisecond electrical switching of the diffraction efficiency at adiffractionangle of 21.4°.","lang":"eng"}],"volume":25,"author":[{"last_name":"Wahle","full_name":"Wahle, M.","first_name":"M."},{"id":"11305","full_name":"Brassat, Katharina","last_name":"Brassat","first_name":"Katharina"},{"last_name":"Ebel","full_name":"Ebel, J.","first_name":"J."},{"first_name":"Julius","id":"46952","full_name":"Bürger, Julius","last_name":"Bürger"},{"first_name":"Jörg","full_name":"Lindner, Jörg","id":"20797","last_name":"Lindner"},{"last_name":"Kitzerow","full_name":"Kitzerow, Heinz-Siegfried","id":"254","first_name":"Heinz-Siegfried"}],"date_updated":"2023-01-10T13:16:11Z","doi":"10.1364/OE.25.022607","has_accepted_license":"1","publication_status":"published","page":"22608-22619","intvolume":"        25","citation":{"ama":"Wahle M, Brassat K, Ebel J, Bürger J, Lindner J, Kitzerow H-S.
