GaAs and GaP (Eg = 2.26 eV) make solid solutions that have the same crystal structure as the parent materials, with As and P randomly distributed throughout the crystal GaPxAs1-x Exists for any value of x. If we assume that the band gap varies linearly with composition between x = 0 and x =1, estimate the band gap for GaP0.5As0.5 .What wavelength of light does this correspond to?
