Abstract: Two-dimensional group-VIB transition metal dichalcogenides (with the formula of MX2) emerge as a family of intensely investigated semiconductors that are promising for both electronic (because of their reasonable carrier mobility) and optoelectronic (because of their direct band gap at monolayer thickness) applications. Effective mass is a crucial physical quantity determining carriers transport, and thus the performance of these applications. Here we present based on first-principles high-throughput calculations a computational study of carrier effective masses of the two-dimensional MX2 materials. Both electron and hole effective masses of different MX2 (M = Mo, W and X = S, Se, Te), including in-layer/out-of-layer components, thickness dependence, and magnitude variation in heterostructures, are systemically calculated. The numerical results, chemical trends, and the insights gained provide useful guidance for understanding the key factors controlling carrier effective masses in the MX2 system and further engineering the mass values to improve device performance.

Key words: high-throughput calculations, two-dimensional materials, transition metal dichalcogenides, carrier effective mass

Fig. 1.  (Color online) Schematic plot of the evolutions of electron and hole energy levels with the sample size L for the semiconductor nanostructures dominated by quantum confinement effect. The evolution of energy can be fitted into the finite potential-well model, ${E_{n}} = \frac{{{n^2}{h^2}}}{{8{m^*}{L^{\rm{\alpha }}}}} + {C_0}$ (see the main text). The larger m* (i.e., the β case) corresponds to a more gradual change in the energy evolution.
