Ga Concentration Effect on the CuIn1-xGaxSe2 Electronic Properties

This paper reports some calculations of the electronic properties of CuIn1-xGaxSe2 (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) compound, by using the Tight-Binding (TB) method and Virtual Crystal Approximation (VCA). It is considered the ideal case and with the tetragonal () and anionic ()...
