Electrical Detection of the Helical Spin Texture in a p-type Topological Insulator Sb2Te3

Abstract

The surface states of 3D topological insulators (TIs) exhibit a helical spin texture with spin locked at right angles with momentum. The chirality of this spin texture is expected to invert crossing the Dirac point, a property that has been experimentally observed by optical probes. Here, we directly determine the chirality below the Dirac point by… (More)
