Spin-dephasing anisotropy for electrons in a diffusive quasi-1D GaAs wire
J. Liu, T. Last, E. J. Koop +3
We present a numerical study of dephasing of electron spin ensembles in a diffusive quasi-one-dimensional GaAs wire due to the D'yakonov-Perel' spin-dephasing mechanism. For widths…
The influence of device geometry on many-body effects in quantum point contacts: Signatures of the 0.7 anomaly, exchange and Kondo
E. J. Koop, A. I. Lerescu, J. Liu +4
The conductance of a quantum point contact (QPC) shows several features that result from many-body electron interactions. The spin degeneracy in zero magnetic field appears to be s…
Valley splitting of Si/SiGe heterostructures in tilted magnetic fields
K. Lai, T. M. Lu, W. Pan +6
We have investigated the valley splitting of two-dimensional electrons in high quality Si/SiGe heterostructures under tilted magnetic fields. For all the samples in our…
Giant spin-orbit splitting in a HgTe quantum well
Y. S. Gui, C. R. Becker, N. Dai +8
We have investigated beating patterns in Shubnikov-de Haas oscillations for HgTe/Hg_{0.3}Cd_{0.7}Te(001) quantum wells with electron densities of 2 to 3 X 10^{12} cm^{-2}. Up to 12…
