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

Spin-relaxation suppression by compensation of bulk and structural inversion asymmetries in [111]-oriented quantum wells
I. Vurgaftman,J. R. Meyer +1 more
TL;DR: In this paper, the feasibility of compensating the bulk inversion asymmetry in a [111]-oriented quantum well with the Rashba structure asymmetry has been investigated and the resulting cancellation is found to provide a promising means for strongly suppressing the spin-relaxation rate associated with the D'yakonov-Perel' (DP) mechanism.
