The field-induced ionization times of the heavy-hole 1s exciton in the miniband field regime are determined from transient four-wave-mixing experiments and theoretical model calculations. They are found to decrease with increasing field, and lie in the picosecond and subpicosecond ranges for fields on the order of a few kV/cm. They are considerably longer than those calculated for a 1s exciton in bulk GaAs. We explain this difference as a result of the nonparabolicities in the superlattice miniband dispersion. In addition to studying the field-induced ionization of the 1s resonance, we also investigate the field dependence of excitonic wave packets composed of both bound and continuum states of the exciton. It is found that the continuum components of the wave packet are more sensitive to low electric fields than the 1s component. © 1996 The American Physical Society.","lang":"eng"}],"publication":"Physical Review-Section B-Condensed Matter","language":[{"iso":"eng"}],"year":"1996","issue":"20","title":"Exciton ionization induced by an electric field in a strongly coupled GaAs/AlxGa1-xAs superlattice","date_created":"2023-04-05T13:41:29Z","status":"public","type":"journal_article","extern":"1","user_id":"49063","department":[{"_id":"293"}],"_id":"43410","citation":{"bibtex":"@article{Meier_von Plessen_Koch_Feldmann_Thomas_Koch_Göbel_Goosen_Kuo_Kopf_1996, title={Exciton ionization induced by an electric field in a strongly coupled GaAs/AlxGa1-xAs superlattice}, volume={53}, DOI={<a href=\"https://doi.org/10.1103/PhysRevB.53.13688\">10.1103/PhysRevB.53.13688</a>}, number={20}, journal={Physical Review-Section B-Condensed Matter}, author={Meier, Torsten and von Plessen, G. and Koch, M. and Feldmann, J. and Thomas, P. and Koch, S.W. and Göbel, E.O. and Goosen,  K.W. and Kuo, J.M. and Kopf, R.F.}, year={1996}, pages={13688–13693} }","short":"T.

Phenomena like Bloch oscillations and negative differential velocity in these structures have been studied using a variety of experimental techniques [1–5]. One particular point of interest has been the transition of the miniband regime to the Bloch oscillation regime with increasing electric field [6,7]. Cw spectra of strongly-coupled superlattices have evidenced that this transition is concomitant with a rapid field-induced ionization of the zero-field miniband exciton [5,8]. While it has been pointed out from the theoretical side that the field-induced ionization process strongly influences the coherent dynamics in the transition region [9], no systematic experimental investigation of the ionization process has been carried out so far. One interesting question that such an investigation could help to answer is to what extent this ionization process differs from the well-documented case of field-induced exciton ionization in bulk semiconductors."}],"date_created":"2023-04-14T22:37:36Z","publisher":"Plenum Press","title":"Field-induced exciton ionization studied by four-wave mixing","year":"1996"},{"_id":"43615","department":[{"_id":"293"}],"series_title":"NATO ASI Series E: Applied Sciences","user_id":"49063","extern":"1","alternative_title":["proceedings of the NATO Advanced Study Institute on Frontiers in Nanoscale Science of Micron/Submicron Devices"],"type":"book_chapter","editor":[{"full_name":"Jauho, A.-P.","last_name":"Jauho","first_name":"A.-P."},{"first_name":"E.V.","full_name":"Buzeaneva, E.V.","last_name":"Buzeaneva"}],"status":"public","date_updated":"2023-05-01T11:00:32Z","volume":328,"author":[{"first_name":"Torsten","id":"344","full_name":"Meier, Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072"},{"full_name":"Koch, S.W.","last_name":"Koch","first_name":"S.W."},{"last_name":"Hader","full_name":"Hader, J.","first_name":"J."},{"last_name":"Je","full_name":"Je, K.-C","first_name":"K.-C"},{"first_name":"F.","last_name":"Rossi","full_name":"Rossi, F."},{"full_name":"Thomas, P.","last_name":"Thomas","first_name":"P."}],"conference":{"end_date":"1995-08-26","location":"Kiev","name":"Proceedings of NATO-ASI","start_date":"1995-08-16"},"main_file_link":[{"url":"https://books.google.de/books?hl=en&lr=&id=lwjmIoBG1cAC&oi=fnd&pg=PA459&dq=info:LCTh7dWMlyoJ:scholar.google.com&ots=jQfJaz3jAn&sig=Hro0qMz7WEzGjkn-taqzbVTu0Zs&redir_esc=y#v=onepage&q&f=false"}],"publication_identifier":{"isbn":["9780792343011"]},"publication_status":"published","place":"Dordrecht","intvolume":"       328","page":"459-478","citation":{"apa":"Meier, T., Koch, S.

The measurements were conducted using time-integrated degenerate-four-wave-mixing in a three-pulse configuration. By choosing particular polarization configurations of the ultrashort optical pulses exciting heavy and light hole excitons simultaneously, degenerate four-wave-mixing signals show either quantum beating or no modulation at all. The experiments are analyzed using a model that takes into account exciton/exciton interaction.","lang":"eng"}],"date_created":"2023-04-14T22:56:51Z","publisher":"Pergamon","title":"Polarization selection rules for quantum beating between light-and heavy-hole excitons in GaAs quantum wells","issue":"5","year":"1995","user_id":"49063","department":[{"_id":"293"}],"_id":"43586","extern":"1","type":"journal_article","status":"public","author":[{"last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344","full_name":"Meier, Torsten","first_name":"Torsten"},{"full_name":"Smith, G.O.","last_name":"Smith","first_name":"G.O."},{"first_name":"E.J.","full_name":"Mayer, E.J.","last_name":"Mayer"},{"first_name":"V.","last_name":"Heuckeroth","full_name":"Heuckeroth, V."},{"first_name":"J.","last_name":"Kuhl","full_name":"Kuhl, J."},{"first_name":"K.","last_name":"Bott","full_name":"Bott, K."},{"first_name":"A.","full_name":"Schulze, A.","last_name":"Schulze"},{"first_name":"D.","full_name":"Bennhardt, D.","last_name":"Bennhardt"},{"last_name":"Koch","full_name":"Koch, S.W.","first_name":"S.W."},{"full_name":"Thomas, P.","last_name":"Thomas","first_name":"P."},{"first_name":"R.","full_name":"Hey, R.","last_name":"Hey"},{"full_name":"Ploog, K.","last_name":"Ploog","first_name":"K."}],"volume":94,"date_updated":"2023-04-14T22:56:54Z","main_file_link":[{"url":"https://www.sciencedirect.com/science/article/abs/pii/0038109895000526"}],"doi":"10.1016/0038-1098(95)00052-6","publication_status":"published","citation":{"mla":"Meier, Torsten, et al. “Polarization Selection Rules for Quantum Beating between Light-and Heavy-Hole Excitons in GaAs Quantum Wells.” <i>Solid State Communications</i>, vol. 94, no. 5, Pergamon, 1995, pp. 373–77, doi:<a href=\"https://doi.org/10.1016/0038-1098(95)00052-6\">10.1016/0038-1098(95)00052-6</a>.","bibtex":"@article{Meier_Smith_Mayer_Heuckeroth_Kuhl_Bott_Schulze_Bennhardt_Koch_Thomas_et al._1995, title={Polarization selection rules for quantum beating between light-and heavy-hole excitons in GaAs quantum wells}, volume={94}, DOI={<a href=\"https://doi.org/10.1016/0038-1098(95)00052-6\">10.1016/0038-1098(95)00052-6</a>}, number={5}, journal={Solid state communications}, publisher={Pergamon}, author={Meier, Torsten and Smith, G.O. and Mayer, E.J. and Heuckeroth, V. and Kuhl, J. and Bott, K. and Schulze, A. and Bennhardt, D. and Koch, S.W. and Thomas, P. and et al.}, year={1995}, pages={373–377} }","short":"T.

The approach allows a kinetic description of the relevant interaction mechanisms such as intra- miniband and interminiband carrier-phonon scattering processes. The energy relaxation of photoexcited carriers, as well as their vertical transport, is investigated in detail. The effects of the multiminiband nature of the superlattice spectrum on the energy relaxation process are discussed with particular emphasis on the presence of Bloch oscillations induced by an external electric field. The analysis is performed for different superlattice structures and excitation conditions. It shows the dominant role of carrier–polar-optical-phonon interaction in determining the nature of the carrier dynamics in the low-density limit. In particular, the miniband width, compared to the phonon energy, turns out to be a relevant quantity in predicting the existence of Bloch oscillations.","lang":"eng"}],"language":[{"iso":"eng"}],"issue":"23","year":"1995","publisher":"American Physical Society","date_created":"2023-04-14T22:52:34Z","title":"Ultrafast carrier relaxation and vertical-transport phenomena in semiconductor superlattices: A Monte Carlo analysis"},{"year":"1995","issue":"20","title":"Signatures of Fano-resonances in four-wave mixing experiments","publisher":"American Physical Society","date_created":"2023-04-14T22:46:56Z","abstract":[{"text":"Optical transitions into discrete levels coupled to an optically active continuum lead to asymmetrical Fano lines in the linear absorption spectra, reflecting interference between the excitation channels.
