Asymmetric tensor in low-symmetry two-dimensional hole systems
C. Gradl, R. Winkler, M. Kempf +8
The complex structure of the valence band in many semiconductors leads to multifaceted and unusual properties for spin-3/2 hole systems compared to typical spin-1/2 electron system…
Decoherence-assisted initialization of a resident hole spin polarization in a two-dimensional hole gas
M. Kugler, K. Korzekwa, P. Machnikowski +9
We investigate spin dynamics of resident holes in a p-modulation-doped GaAs/AlGaAs single quantum well. Time-resolved Faraday and Kerr rotation, as well as resonant…
Spin dynamics in p-doped semiconductor nanostructures subject to a magnetic field tilted from the Voigt geometry
K. Korzekwa, C. Gradl, M. Kugler +9
We develop a theoretical description of the spin dynamics of resident holes in a p-doped semiconductor quantum well (QW) subject to a magnetic field tilted from the Voigt geometry.…
Hole spin dynamics and hole factor anisotropy in coupled quantum well systems
C. Gradl, M. Kempf, D. Schuh +4
Due to its p-like character, the valence band in GaAs-based heterostructures offers rich and complex spin-dependent phenomena. One manifestation is the large anisotropy of Zeeman s…
