Abstract
Confined TO and LO photon frequencies of (GaAs)m(AlAs)n superlattices with 1 less-than-or-equal-to m, n less-than-or-equal-to 7 are measured by means of far-infrared reflectivity and Raman scattering, respectively, and compared with those calculated in the framework of an ab-initio scheme for superlattices with abrupt interfaces.
