Description:
Large quantum-spin-Hall gap in single-layer 1 T ′ WSe 2 Large quantum-spin-Hall gap in single-layer 1〈i〉T〈/i〉′ WSe〈sub〉2〈/sub〉, Published online: 21 May 2018; doi:10.1038/s41467-018-04395-2 The current known two-dimensional topological insulators with small band gaps limit the potential for room temperature applications. Here, Chen et al. observe a sizable gap of 129 meV in a 1T'-WSe2 single layer grown on bilayer graphene with in-gap edge state near the layer boundary.
