Anomalous spin dephasing in (110) GaAs quantum wells: Anisotropy and intersubband effects

Döhrmann, S.; Hägele, D.; Rudolph, J.; Bichler, M.; Schuh, D.; Oestreich, Michael (College Park, MD : American Physical Society, 2004)

The anisotropic spin dephasing in (110) quantum wells (QW) from 6 K up to room temperature was investigated. It was found that intersubband scattering constitutes a new spin dephasing mechanism that is necessary to explain ...
Giant anisotropy of zeeman splitting of quantum confined acceptors in Si/Ge

Haendel, K.-M.; Winkler, R.; Denker, U.; Schmidt, O.G.; Haug, Rolf J. (College Park, MD : American Physical Society, 2006)

Shallow acceptor levels in Si/Ge/Si quantum well heterostructures are characterized by resonant-tunneling spectroscopy in the presence of high magnetic fields. In a perpendicular magnetic field we observe a linear Zeeman ...
Magnetoresistance anisotropy in Si/SiGe in tilted magnetic fields: Experimental evidence for a stripe-phase formation

Zeitler, U.; Schumacher, Hans W.; Jansen, A.G.M.; Haug, Rolf J. (College Park, MD : American Physical Society, 2001)

The anisotropies induced by an in-plane field in the magnetotransport properties of coinciding Landau levels in the two dimensional electron system of a silicon/silicon germanium (Si/SiGe) heterostructure were investigated. ...
