The vertical stacking of various two-dimensional (2D) layered materials to create van der Waals heterostructures (vdWHs) has received great attention as a promising material for developing nanoelectronic and optoelectronic devices. This is because such structures can inherit the unique favorable properties single 2D material. In this study, SnSe2/MoSe2 vdWH model was built first time using first-principles approach, its electronic optical were systematically investigated. results reveal that...
We calculate the generalized stacking fault (GSF) energies and cleavage γcl of chalcopyrite compounds CuAlSe2, CuGaSe2, CuInSe2, CuGaS2 CuGaTe2 using first principles. From GSF energies, we obtain unstable γus intrinsic γisf. By analyzing γisf, find that (1 1 2) direction is easiest slip for these five compounds. Also, it most possible to undergo a dislocation-nucleation-induced plastic deformation along direction. show plane preferable fracture in by comparing (0 0 1) planes. It also found...
