Bowing parameter
WebThe bowing parameter, b GaInAs, describes deviation from a linear interpolation. This parameter is assumed to be the same as for N-free ternary alloy (i.e., Ga 1 − x In x As alloy) and is taken from Ref. [176] . WebFor InGaN a bowing parameter =1.4 eV in agreement with the work of Walukievicz et al. is well established. It corresponds to the theoretical value given by Caetano et al. (=1.44 …
