| Description
| - Práce je venována luminiscenci dvojité kvantové jámy (DQW) v systému GaAs/AlGaAs ve vysokých magnetických polích. Merení byla provedena na selektivne; kontaktované p-dn-DQW-dn-p strukture umožnující priložením naprtí p-n zmenu koncentrace elektronu; v DQW a zároven; pomocí napetí p-p její naklánení. Pozornost byla venována prdevším efektum indukovaným v in-plane magnetickém poli, které teoreticky studovali Huang a Lyo (HL) [Phys. Rev. B 59, (1999) 7600]. V této práci srovnáváme naše experimentální výsledky s efekty predpovezenými v citované teoretické práci. Zatímco výsledky na symetrické DQW plneni; potvrdily ocekávání, experiment na DQW s elektrickým polem indukovanou asymetrií nedovolily podrobné overení teoretických predpovedi. (cs)
- We report on photoluminescence (PL) measurements of a GaAs/AlGaAs double quantum well (DQW) in high magnetic fields. Measurements were carried out on a selectively contacted symmetric p-dn-DQW-dn-p structure, which allows a variation of the electron density in DQW by a pn bias and simultaneously a tilting of DQW, when a pp bias is applied. Attention was paid to phenomena in inplane magnetic firlds, theoretically studied by Huang and Lyo (HL), [Phys. Rev. B 59, (1999) 7600]. In this paper, we compare our results for both symmetric and asymmetric DQWs with the theoretical model made by HL. Whereas the spectra from a symmetric DQW fully confirmed the theoretical predictions, the results gained from DQW with an electric-field-induced asymmetry did not allow a proper study of anticipated effects. The reasons for that are discussed.
