As precursor gases silane (SiH4), nitrous oxide (N2O), nitrogen (N2) and ammonia (NH3) are used with different compositions. We find that for achieving high nitrogen content adding ammonia to the precursor mix is most efficient. Moreover, we investigate the balance between adsorption and desorption processes during film growth by investigating the film growth rate as a function of the substrate temperature. From these data we are able to determine an effective activation energy for the film growth, corresponding to the difference between adsorption and desorption energy. Finally, we have thoroughly investigated the optical properties of the films using spectroscopic ellipsometry. From these measurements, we suggest a parametrized model for the refractive index and extinction coefficient in a wide range of compositions based on a Cauchy- and a Lorentz-fit.","lang":"eng"}],"article_type":"original","language":[{"iso":"eng"}],"doi":"10.1016/j.tsf.2021.138887","date_updated":"2022-01-06T06:56:00Z","project":[{"name":"TRR 142","_id":"53"},{"name":"TRR 142 - Project Area B","_id":"55"},{"_id":"66","name":"TRR 142 - Subproject B1"}],"publication_status":"published","publication_identifier":{"issn":["0040-6090"]},"department":[{"_id":"15"}],"title":"Optical properties of silicon oxynitride films grown by plasma-enhanced chemical vapor deposition"},{"doi":"10.1016/j.tsf.2016.03.053","_id":"15732","date_updated":"2022-01-06T06:52:32Z","page":"143-147","citation":{"short":"H.

These substrates are of interest for the epitaxial growth of III–V compound semiconductor stacks on their top for the production of multi-junction solar cells and very thin electronic devices. We demonstrate transfer of porous layers after an annealing process in hydrogen atmosphere. Electron Back-Scatter Diffraction analysis confirms that the substrate orientation is conserved during the etching and annealing steps. Confocal μ-Raman spectroscopy analysis shows a decrease in the Raman signal intensity after etching and a subsequent increase after annealing while no shift is observed. By means of Atomic Force Microscopy, analysis the surface appearance after the etching and annealing steps can be visualized. The mean surface roughness varies during the process from 0.55 nm for the unprocessed wafers to 0.27 nm after etching and 0.78 nm after annealing. The decrease of average roughness after etching is caused by an electropolishing step prior to porous formation. Despite of slight increase of mean surface roughness after annealing the samples are still appropriate for high quality epitaxial growth and subsequent lift-off.","lang":"eng"}],"status":"public","date_created":"2018-09-11T14:21:12Z","volume":520,"publisher":"Elsevier BV","author":[{"full_name":"Garralaga Rojas, E.","first_name":"E.","last_name":"Garralaga Rojas"},{"last_name":"Terheiden","full_name":"Terheiden, B.","first_name":"B."},{"first_name":"H.","full_name":"Plagwitz, H.","last_name":"Plagwitz"},{"last_name":"Hensen","full_name":"Hensen, J.","first_name":"J."},{"last_name":"Wiedemeier","first_name":"V.","full_name":"Wiedemeier, V."},{"id":"53","last_name":"Berth","full_name":"Berth, Gerhard","first_name":"Gerhard"},{"last_name":"Zrenner","id":"606","first_name":"Artur","full_name":"Zrenner, Artur","orcid":"0000-0002-5190-0944"},{"last_name":"Brendel","full_name":"Brendel, R.","first_name":"R."}],"keyword":["Porous Si","Layer transfer","Thin-film","Photovoltaics"],"publication":"Thin Solid Films","issue":"1","_id":"4379","intvolume":" 520","year":"2011","citation":{"mla":"Garralaga Rojas, E., et al. “Lift-off of Mesoporous Layers by Electrochemical Etching on Si (100) Substrates with Miscut of 6° off towards (111).” Thin Solid Films, vol. 520, no. 1, Elsevier BV, 2011, pp. 606–09, doi:10.1016/j.tsf.2011.07.063.","bibtex":"@article{Garralaga Rojas_Terheiden_Plagwitz_Hensen_Wiedemeier_Berth_Zrenner_Brendel_2011, title={Lift-off of mesoporous layers by electrochemical etching on Si (100) substrates with miscut of 6° off towards (111)}, volume={520}, DOI={10.1016/j.tsf.2011.07.063}, number={1}, journal={Thin Solid Films}, publisher={Elsevier BV}, author={Garralaga Rojas, E. and Terheiden, B. and Plagwitz, H. and Hensen, J. and Wiedemeier, V. and Berth, Gerhard and Zrenner, Artur and Brendel, R.}, year={2011}, pages={606–609} }","ama":"Garralaga Rojas E, Terheiden B, Plagwitz H, et al.

Mesoporous SnO2 doped with palladium species was prepared and exposed to different gas mixtures at high temperature (600 °C) to simulate long term usage. After each exposure step a fraction of the sample was cooled down to “freeze” the current oxidation state of Pd which was then analyzed by X-ray Absorption Near-Edge Spectroscopy (XANES) using the 'white line' (i.e. the absorption peak corresponding to the transition from the 2p3/2 core level to unoccupied 4 d states) intensity of the L(III) edge as a probe for the oxidation state. The Pd oxidation state correlates with the response of the resistive SnO2 sensor to methane gas, as determined by measuring the gas response to different concentrations of methane. Samples treated with 5000 ppm methane in air show a significant reduction of Pd(II) to Pd(0), depending clearly on the carrier gas (synthetic air, pure nitrogen) and on the temperature (600 °C vs. 300 °C)."}],"article_type":"original"},{"date_updated":"2023-03-09T08:29:14Z","_id":"25961","doi":"10.1016/j.tsf.2011.04.181","type":"journal_article","year":"2011","citation":{"apa":"Wagner, T., Hennemann, J., Kohl, C.-D., & Tiemann, M.
