Thickness-dependent structural stability and transition in molybdenum disulfide under hydrostatic pressure
Dong Jiansheng, Ouyang Gang
       

Phase diagram of MoS2 under the condition of hydrostatic pressure. The blue line represents the boundary between 2Hc and 2Ha phases. There is no interlayer interaction in monolayer represented by 2H phase. The semiconductor to metal transition is separated by the red line, while the pale green region denotes semiconducting.
