Helical edge and surface states in HgTe quantum wells and bulk insulators

Abstract

The quantum spin Hall (QSH) effect is the property of a new state of matter which preserves time reversal, has an energy gap in the bulk, but has topologically robust gapless states at the edge. Recently, the QSH state has been theoretically predicted and experimentally observed in HgTe quantum wells [B. A. Bernevig et al., Science 34, 1757 (2006); M. Konig et al., ibid. 318, 766 (2007)]. In this work, we start from realistic tight-binding models and demonstrate the existence of the helical edge states in HgTe quantum wells and calculate their physical properties. We also show that three-dimensional HgTe is a topological insulator under uniaxial strain and show that the surface states are described by single-component massless relativistic Dirac fermions in $2+1$ dimensions. Experimental predictions are made based on the quantitative results obtained from realistic calculations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
