| Abstract: | he second order approximation wave function of a polaron in a ternary mixed crystal is de-rived by a pertubation method,the polarization potential and the polarized charge density of aelectron are also calculated.The numerical results are given for Al_xGa_(1-x)As and ZnTe_xSe_(1-x) with different composition x,and the results are discussed. |
