Coulomb Interaction and Wannier-Mott Excitons in Polar Semi-Conducting Quantum Wires
Abstract:Under theoretical investigation are the Coulomb interaction and exiton Wannier-Mott states in polar semi-conducting quantum wires in the dielectric environment. It is shown that alongside the effects of dimensional (geometrical) and dielectric intensification of Coulomb interaction between the electron and the hole there takes place an extra effect of exiton binding energy growth conditioned by the "loss" of part of inertial screening. Estimations have been done of the shifting of exiton peaks, caused by this effect, in the optical spectrum for quantum wires of cadmium selenide and gallium arsenide in the dielectric matrix.
