| Structural and electronic properties of the 2H-MX2 (M = Mo, W; X = S, Se, Te) monolayers are investigated in terms of density functional theory methods. A comparison of structural parameters, energy gaps and spin-orbit coupling driven splittings obtained with different pseudopotential methods and various parametrization of exchange-correlation functional is presented. |
