TLDR
In this article, a character table for the group of the wave vector at certain points of symmetry in the Brillouin zone is given, and a possible reason for the complications which may make a simple effective mass concept invalid for some crystals of this type structure is presented.Abstract:
Character tables for the "group of the wave vector" at certain points of symmetry in the Brillouin zone are given. The additional degeneracies due to time reversal symmetry are indicated. The form of energy vs wave vector at these points of symmetry is derived. A possible reason for the complications which may make a simple effective mass concept invalid for some crystals of this type structure will be presented.read more

Multisubband effect in spin dephasing in semiconductor quantum wells
M. Q. Weng,M. W. Wu +1 more
TL;DR: In this article, the effects of temperature, well width, and applied electric field (in a hot-electron regime) on spin kinetics are thoroughly investigated, and it is shown that due to the strong inter-subband scattering, the spin procession and the spin dephasing rate of electrons in different subbands are almost identical despite the large difference in the D'yakonov-Perel' (DP) terms of different sub bands.

Drift–diffusion approach to spin-polarized transport
TL;DR: In this paper, a drift-diffusion equation was developed to describe electron spin polarization density in two-dimensional electron systems, where the Dresselhaus and Rashba spin-orbit coupling mechanisms were taken into consideration, as well as an applied electric field.
