Starting from the relaxed atomic geometries, we analyze the influence of self-energy corrections on the electronic band structure within the GW approximation. We find that quasiparticle shifts widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64) eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic and local-field effects, which turn out to be essential for good agreement with experimental data. From our results, we extract an exciton binding energy of 0.6, 0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively. Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both theoretically and experimentally. The frequency-dependent second-order polarization tensor of orthorhombic KNbO3 is measured for incoming photon energies between 1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle approximation are performed for the tetragonal and orthorhombic phase. The novel experimental data are in excellent agreement with the quasiparticle calculations and resolve persistent discrepancies between earlier experimental measurements and ab initio results reported in the literature.","lang":"eng"}],"file":[{"file_name":"PhysRevMaterials.3.054401.pdf","access_level":"open_access","file_size":1949504,"relation":"main_file","date_updated":"2020-08-30T14:34:33Z","file_id":"18465","content_type":"application/pdf","title":"Quasiparticle and excitonic effects in the optical response of KNbO3","creator":"schindlm","date_created":"2020-08-27T19:05:54Z","description":"© 2019 American Physical Society"}],"date_created":"2019-05-29T06:55:29Z","type":"journal_article","department":[{"_id":"295"},{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"170"},{"_id":"35"}],"year":"2019","title":"Quasiparticle and excitonic effects in the optical response of KNbO3","publication_identifier":{"eissn":["2475-9953"]},"author":[{"id":"35251","full_name":"Schmidt, Falko","first_name":"Falko","last_name":"Schmidt","orcid":"0000-0002-5071-5528"},{"last_name":"Riefer","first_name":"Arthur","full_name":"Riefer, Arthur"},{"orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero","full_name":"Schmidt, Wolf Gero","id":"468"},{"id":"458","full_name":"Schindlmayr, Arno","last_name":"Schindlmayr","orcid":"0000-0002-4855-071X","first_name":"Arno"},{"first_name":"Mirco","last_name":"Imlau","full_name":"Imlau, Mirco"},{"first_name":"Florian","last_name":"Dobener","full_name":"Dobener, Florian"},{"full_name":"Mengel, Nils","last_name":"Mengel","first_name":"Nils"},{"first_name":"Sangam","last_name":"Chatterjee","full_name":"Chatterjee, Sangam"},{"full_name":"Sanna, Simone","first_name":"Simone","last_name":"Sanna"}],"publication_status":"published","date_updated":"2023-04-20T14:20:33Z","article_type":"original","intvolume":"         3","article_number":"054401","language":[{"iso":"eng"}],"doi":"10.1103/PhysRevMaterials.3.054401"},{"volume":99,"user_id":"16199","_id":"29746","publisher":"American Physical Society (APS)","status":"public","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"TRR 142: TRR 142","_id":"53"},{"_id":"55","name":"TRR 142 - B: TRR 142 - Project Area B"},{"name":"TRR 142 - B4: TRR 142 - Subproject B4","_id":"69"}],"citation":{"bibtex":"@article{Nicholson_Puppin_Lücke_Gerstmann_Krenz_Schmidt_Rettig_Ernstorfer_Wolf_2019, title={Excited-state band mapping and momentum-resolved ultrafast population dynamics in In/Si(111) nanowires investigated with XUV-based time- and angle-resolved photoemission spectroscopy}, volume={99}, DOI={<a href=\"https://doi.org/10.1103/physrevb.99.155107\">10.1103/physrevb.99.155107</a>}, number={15155107}, journal={Physical Review B}, publisher={American Physical Society (APS)}, author={Nicholson, C.

Within the independent-particle approximation an electronic transport gap of 2.97 eV is obtained that widens to about 5.23 eV when quasiparticle effects are included using the GW approximation. The optical response is shown to be strongly anisotropic due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii) their anisotropic distribution along the [001] and [100] directions. In addition, excitonic effects are very important: The solution of the Bethe–Salpeter equation indicates exciton binding energies of the order of 1.5 eV. Calculations that include both quasiparticle and excitonic effects are in good agreement with the measured reflectivity."}],"date_created":"2019-09-19T14:34:16Z","file":[{"creator":"schindlm","description":"Creative Commons Attribution 3.0 Unported Public License (CC BY 3.0)","date_created":"2020-08-28T09:07:18Z","relation":"main_file","date_updated":"2020-08-30T14:29:27Z","file_name":"Neufeld_2019_J._Phys._Mater._2_045003.pdf","access_level":"open_access","file_size":1481174,"title":"Potassium titanyl phosphate (KTP) quasiparticle energies and optical response","file_id":"18535","content_type":"application/pdf"}],"department":[{"_id":"296"},{"_id":"295"},{"_id":"230"},{"_id":"429"},{"_id":"170"},{"_id":"35"}],"type":"journal_article","status":"public","has_accepted_license":"1","publisher":"IOP Publishing","_id":"13365","page":"045003","volume":2,"ddc":["530"],"user_id":"171","isi":"1","citation":{"short":"S.

We show that such a\r\nmodel takes the form of a generalized Lotka-Volterra system for two competing\r\npopulations explicitly including a source term that enables external control.\r\nWe present a comprehensive analysis both of the existence and stability of\r\nstationary states in the parameter space spanned by spatial anisotropy and\r\nexternal control strength. We also construct phase boundaries in non-trivial\r\nregions and characterize emerging bifurcations. The population competition\r\nmodel reproduces all key features of the switching observed in full numerical\r\nsimulations of the rather complex semiconductor system and at the same time is\r\nsimple enough for a fully analytical understanding of the system dynamics."}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}]},{"_id":"13347","language":[{"iso":"eng"}],"user_id":"16199","title":"Molecular Doping of PCPDT-BT Copolymers: Comparison of Molecular Complexes with and Without Integer Charge Transfer","year":"2019","status":"public","author":[{"last_name":"Dong","first_name":"Chuan-Ding","full_name":"Dong, Chuan-Ding","id":"67188"},{"first_name":"Stefan","orcid":"0000-0003-4042-4951","last_name":"Schumacher","full_name":"Schumacher, Stefan","id":"27271"}],"date_updated":"2025-12-05T14:31:11Z","publication_status":"published","date_created":"2019-09-19T13:44:34Z","type":"preprint","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"230"},{"_id":"35"},{"_id":"27"}],"citation":{"bibtex":"@article{Dong_Schumacher_2019, title={Molecular Doping of PCPDT-BT Copolymers: Comparison of Molecular Complexes with and Without Integer Charge Transfer}, author={Dong, Chuan-Ding and Schumacher, Stefan}, year={2019} }","ama":"Dong C-D, Schumacher S.

In the present work we theoretically investigate p-type molecu-\r\nlar doping in a series of (poly[2,6-(4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b”]dithiophene)-alt-\r\n4,7-(2,1,3-benzothiadiazole)] (PCPDT-BT) conjugated oligomers with different lengths and three\r\nwidely-used dopants with different electron affinities, namely F4TCNQ, F6TCNNQ, and CN6-CP.\r\nWe study in detail the molecular geometry of possible oligomer-dopant complexes and its influence\r\non the doping mechanisms and electronic system properties. We find that the mechanisms of dop-\r\ning and charge transfer observed sensitively depend on the specific geometry of the oligomer-dopant\r\ncomplexes. For a given complex different geometries may exist, some of which show transfer of\r\nan entire electron from the oligomer chain onto the dopant molecule resulting in an integer-charge\r\ntransfer complex, leaving the system in a ground state with broken spin symmetry. In other ge-\r\nometries merely hybridization of oligomer and dopant frontier orbitals occurs with partial charge\r\ntransfer but spin-symmetric ground state. Considering the resulting electronic density of states both\r\ncases may well contribute to an increased electrical conductivity of corresponding film samples while\r\nthe underlying physical mechanisms are entirely different.\r\n&lt;/p&gt;\r\n\t\t\t\t&lt;/div&gt;\r\n\t\t\t&lt;/div&gt;\r\n\t\t&lt;/div&gt;</jats:p>","lang":"eng"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}]},{"status":"public","volume":123,"user_id":"16199","_id":"13343","page":"4483-4492","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"citation":{"short":"J.
