Abstract:

The authors predict the multiphonon absorption alpha in amorphous solids, using the statistical theory of Mitra et al, which relates optical properties of amorphous solids to variations in their local density. As an application of the method, they perform calculations are performed for III-V semiconductors using an exactly soluble single-particle model which accounts for both anharmonicity and nonlinear moments. Broadening of alpha and suppression of the temperature dependence is predicted to occur to varying extents for the III-Vs investigated. This suggests that various amorphous solids may not be as attractive as their crystalline counterparts for infrared applications requiring high transparency.
