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

Relativistic Energy Bands of HgTe and HgSe
TL;DR: In this paper, the electronic band structures of HgTe and HgSe have been calculated using the relativistic Green's function method using reflectivity data, and a valence band overlap is found which is in agreement with the estimate given by Verie.

Ab initio approach to structural, electronic, and ferroelectric properties of antimony sulphoiodide
Danila Amoroso,Silvia Picozzi +1 more
TL;DR: In this paper, the authors show that bare density functional theory fails to reproduce the experimentally observed ferroelectric phase, whereas a more advanced approach, based on hybrid functionals, correctly works.

Relaxation mechanisms of the persistent spin helix
TL;DR: In this paper, the lifetime of the persistent spin helix in semiconductor quantum wells with equal Rashba and linear Dresselhaus spin-orbit coupling strengths was studied and it was shown that even longer lifetimes can be achieved by generating a spatially damped spin profile.

Spin and phase coherence lengths in n-InSb quasi-one-dimensional wires
TL;DR: In this article, the magnetoconductance of quasi-one-dimensional wires fabricated on a two-dimensional electron system in an InSb/InAlSb heterostructure was examined by analyzing the magneto-conductance in antilocalization theory modified to account for ballistic transport.

Effect of Time-Reversal Symmetry on Energy Bands of Crystals
TL;DR: In this paper, a criterion is developed to facilitate calculation of when and how such additional degeneracy will occur, and the consequences of the reality of the Hamiltonian are tabulated for a number of cases.
