摘要：
The dielectric continuum model of longitudinal-optical phonons in polar semiconductors is used to define the role of interface longitudinal-optical phonons- in affecting phonon-assisted GAMMA-x transitions in GaAs-AlAs and GaAs-GaP superlattices. In particular, the dielectric continuum model for interface optical phonons is used in conjunction with a Kronig-Penney model of the superlattice electronic properties for two purposes: to specify superlattice parameters where interface-phonon-assisted GAMMA-X transitions are expected and to estimate relative transition probability amplitudes for interface-phonon-assisted GAMMA-x transitions in selected short-period superlattices.
