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

Weak antilocalization in gate-controlled Al x Ga 1 − x N ∕ Ga N two-dimensional electron gases
TL;DR: Weak antilocalization and the Shubnikov\char21{}de Haas effect were investigated in two-dimensional electron gases as mentioned in this paper, where a constant spin-orbit scattering length was revealed, which does not change if the Al content or the thickness of the barrier layer is varied.

Dyakonov‐Perel Effect on Spin Dephasing in n‐Type GaAs
TL;DR: In this paper, the authors studied the spin dephasing in n-doped bulk GaAs under moderate magnetic fields in Voigt configuration due to the Dyakonov-Perel (DP) effect by constructing and numerically solving the kinetic Bloch equations.

TL;DR: In this paper, the authors applied time-resolved circular dichroism techniques to the study of carrier spin dynamics in a 2D perovskite thin film and confirmed the presence of a Rashba spin splitting via the dominance of precessional spin relaxation induced by the D'yakonov Perel spin relaxation.

TL;DR: This work establishes a clear connection between the overall strength of the band splitting and the charge transfer between the d-orbitals at the interface, and shows that the spin splitting of the Fermi surface scales with the induced orbital moment, weighted by the spin-orbit coupling.
