Interaction-assisted propagation of Coulomb-correlated electron-hole pairs in disordered semiconductors
arXiv:cond-mat/0002399 · doi:10.1007/s100510050837
Abstract
A two-band model of a disordered semiconductor is used to analyze dynamical interaction induced weakening of localization in a system that is accessible to experimental verification. The results show a dependence on the sign of the two-particle interaction and on the optical excitation energy of the Coulomb-correlated electron-hole pair.
