Room-temperature quantum spin Hall phase in laser-patterned few-layer 1T′- MoS2

The quantum spin Hall (QSH) phase is an important feature of two dimensional topological insulators and is typically observed at temperatures below 100 K. Here, the authors report the observation of a room temperature quantum spin Hall phase in few-atom-layer 1T′-MoS2 patterned onto the 2H semicondu...
