Binding energy of excitonic molecules in isotropic semiconductors

Abstract

AbstractThe solution of the Schrödinger equation of the excitonic molecule system has been expanded using Feynman's path integral method, in order to determine the binding energy of the excitonic molecules. For the numerical treatment the Monte‐Carlo method was used. The results show that for the case of comparable mass size of electron and hole the method used is more general and satisfactory than the calculations up to the present time. Good agreement with experimental observations is obtained for the complexes in Cu Br, CuCl, CdS, Cu2O, CdSe, Ge, and Si.
