Question: GaAs 1x P x has a unit-cell parameter of 5.59 . Calculate x and estimate the band gap(E g ) of the material, given aGaAs

GaAs1−xPx has a unit-cell parameter of 5.59 Å. Calculate x and estimate the band gap(Eg) of the material, given

aGaAs = 5.65 , Eg = 1.42 eV; aGap = 5.45 , E = 2.24 eV.

aGaAs = 5.65 , Eg = 1.42 eV; aGap = 5.45 , E = 2.24 eV.
