EXCITONIC OPTICAL-PROPERTIES IN SEMICONDUCTOR THIN QUANTUM BOXES OF INTERMEDIATE REGIME BETWEEN ZERO AND 2 DIMENSIONS

We discuss the optical properties in thin quantum boxes based on a the oretical analysis that rigorously treats excitonic confinement effects in the intermediate regime between zero and two dimensions. Our theor y can exactly analyze not only the excitonic ground state but also hig her energy states, and thus can simulate whole absorption spectra near the band edge region. We also report novel exciton electro-absorption effects found in the intermediate confinement regime. (C) 1996 Americ an Institute of Physics.
