Dependence of Optical Deformation Potential Constant on the Masses and the Composition Ratios of Constituent Atoms

The mass dependence of the optical deformation potential constant for non-polar optical phonon scattering in the valence band of compound and alloy semiconductors is theoretically derived by employing a linear spring model. A huge number of force equations are used in the spring model in order to account for the random array of various atoms whereas only two solutions are assumed in consideration of the experimental data. The result of this work explains the dependence of the optical deformation potential constant on the masses and the composition ratios of constituent atoms for compound and alloy semiconductors.
