摘要：

A two-band model with a local electron-hole interaction is used to calculate the binding energy of a direct exciton for arbitrary carrier density. For parabolic bands and in Thomas-Fermi approximation simple expressions for binding energy and Mott density are obtained. Comparison with existing theories and experiments is made. © 1979.
