Direct measurements of the spin and valley splittings in the magnetization of a SiSiGe quantum well in tilted magnetic fields

Wilde, M.A.; Rhode, M.; Heyn, C.; Heitmann, D.; Grundler, D.; Zeitler, U.; Schäffler, F.; Haug, Rolf J. (College Park, MD : American Physical Society, 2005)

We present de Haas-van Alphen (dHvA) measurements on high-mobility two-dimensional electron systems formed in modulation-doped SiSiGe (100) quantum wells and demonstrate directly the manifestation of the valley splitting ...
Energy band modulation of GaAs/Al0.26Ga0.74As quantum well in 3D self-assembled nanomembranes

Zhang, Fei; Huang, GaoShang; Nie, XiaoFei; Cao, Xin; Ma, Zhe; Ding, Fei; Di, ZengFeng; Zhen, HongLou; Mei, YongFeng (Amsterdam : Elsevier, 2019)

In this study, we investigate the modulation of energy band in 3D self-assembled nanomembranes containing GaAs/Al0.26Ga0.74As quantum wells (QWs). Photoluminescence (PL) characterizations demonstrate that the self-assembled ...
Zeeman splitting of zero-dimensional heavy-hole states in a strongly strained Ge quantum well

Agafonov, Oleksiy B.; Haendel, K.-M.; Winkler, R.; Denker, U.; Schmidt, O.G.; Haug, Rolf J. (College Park, MD : American Institute of Physics, 2007)

The method of magnetotunneling spectroscopy has been used for experimental probing of heavy-hole impurity states in Si/Ge double-barrier heterostructures in magnetic field up to 18 Tesla. The impurities were located in a ...
