TL;DR: In this article, the transport properties of the semiconductor HgTe-based quantum well, recently shown to be a two-dimensional topological insulator, are studied experimentally in the diffusive regime.
Journal ArticleDOI
Cyclotron resonance studies on bulk and two-dimensional conduction electrons in InSe
TL;DR: In this paper, the conduction band is shown to exhibit an anomalous anisotropy with m ∥ = 0.08 m 0 and m ⊥= 0.14 m 0.
