First Principles Study on Electronic Structure and Optical Properties of Ternary GaAs:Bi Alloy
The electronic structure and optical properties of ternary GaAs:Bi alloy are investigated by first principles calculations. It is found that the band gap of GaAs1-xBix decreases monotonously with the increasing of Bi concentration, resulting in the fundamental absorption edge and main absorption pea...
