Metal Dichalcogenides

Two-dimensional (2D) layered materials such as transition-metal dichalcogenides TS[Formula: see text]X[Formula: see text] (T = Mo, W; X = Se, Te) are available in mono and bilayers forms. The Rashba spin splitting is induced by the breaking of inversion symmetry in monolayer. The electronic structure of TS[Formula: see text]X[Formula: see text] is sensitive to an applied electric field. The perpendicular electric field can tune the energy gap. The semiconductor–metal transition appears under the critical electric field in the MoSSe/WSSe heterobilayer, and MoSTe/WSTe heterobilayer exhibits metal character due to spin–orbit coupling. Moreover, the results show that during sodiation/desodiation processes single-phase transition occurs with one one-dimensional (1D) transportation paths of sodium ions in MoS2, suggesting fast diffusion. Our results provide important insights into a wide range of applications of spin-polarized semiconductors and energy storage for transition-metal dichalcogenides TS[Formula: see text]X[Formula: see text].

Two-dimensional Janus transition-metal dichalcogenides possess an intrinsic Rashba effect, which can be manipulated by charge doping. Electron doping can effectively strengthen the Rashba effect, while hole doping would weaken it.

Metal Dichalcogenides

Due to the introduction of morphological control, the excitons are pushed towards the regions with higher stress. In addition, combined with intrinsic electric field, a spatial separation of photo-excited electrons and holes is achieved.
