ELECTRON-OPTICAL-PHONON INTERACTION IN BINARY TERNARY HETEROSTRUCTURES

The macroscopic dielectric continuum model is used to derive electron-optical-phonon interaction Hamiltonians for binary/ternary heterostructures containing both single and double heterointerfaces. The formulation presented in this work leads to a general prescription for the calculation of mode-strength coefficients in ternary-containing heterostructures. An illustration of these results is provided by exhibiting the mode strengths of the interaction Hamiltonians for the interface and the half-space longitudinal optical modes in a GaAs/Al(y)Ga(1-y)As single heterostructure.
