Abstract |
|
|
|
Electronic and optical properties of AII-BIV-CV2 family, where II=Be, Mg, Zn, Cd; IV=Si, Ge, Sn; V=P, As, are calculated using the Vienna ab initio simulation package (VASP) with ultrasoft pseudopotentials and full-potential linearized augmented plane wave (FLAPW) method. The tendency of lattice constants changes upon variation of the group IV atoms is established and materials with best fitting to semiconducting usual substrates are determined. Recommendations upon perspectives for photovoltaics of such materials are given.
