Realizing robust large-gap quantum spin Hall state in 2D HgTe monolayer on insulating substrate
Can Qi, Liying Ouyang, Jun Hu
Although many possible two-dimensional (2D) topological insulators (TIs) have been predicted in recent years, there is still lack of experimentally realizable 2D TI. Through first-…

Alloying-induced topological transition in 2D transition-metal dichalcogenide semiconductors
Liying Ouyang, Ge Hu, Can Qi +1
Research on two-dimensional (2D) topological insulators (TIs) is obstructed due to the lack of feasible approaches to growing 2D TIs in experiments. Through systematic first-princi…
