We have theoretically studied the electronic and optical properties of a quantum well (QW) in which the well region is constructed from a binary alloy semiconductor A 1--x B x in the coherent potential approximation (CPA). A tight binding model is used for a single particle (electron, hole, Frenkel
An analysis of normal modes observed in measurements of reflection, transmission, and true absorption is presented. It is found that individual modes can be identified and sometimes resolved as dips in reflection measurements, and peaks in transmission measurements. The split mode energy ``bandsΒΊ ar
