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

Electrical generation of pure spin current with oscillating spin-orbit interaction

TL;DR: In this article, an electrical scheme for the generation of a pure spin current without a charge current in a two-terminal device, which is composed of a scattering region of a 2DEG with Rashba (R) and/or Dresselhaus (S) spin-orbit interaction (SOI) and two normal leads, is proposed.

Novel IV–V–VI semiconductors with ultralow lattice thermal conductivity
TL;DR: In this article, a group of 56 novel layered semiconducting IV-V-VI (IV = Si, Ge Sn, Pb; V = As, Sb, Bi; VI = S, Se, Te) compounds are shown to exhibit intrinsically ultralow lattice thermal conductivity between 0.28 and 2.02 W m−1 K−1 at room temperature.

Spin characterization and control over the regime of radiation-induced zero-resistance states
TL;DR: A low-magnetic-field analog of quantum-Hall-limit techniques for the electrical detection of electron spin and nuclear magnetic resonance, dynamical nuclear polarization via electron spin resonance, and electrical characterization of the nuclear spin polarization via the Overhauser shift was proposed in this paper.

Spin–orbit gauge and quantum spin Hall effect
TL;DR: In this article, it was shown that the non-Abelian spin-orbit gauge field strength of the Rashba and Dresselhaus interactions, when split into two Abelian field strengths, can be re-expressed as a Landau level problem with a particular relation between the two coupling parameters.
