摘要
The electronic structure of a polar semiconductor film is investigated by using the Green's function method. The tight-binding approximation is employed to model the polar semiconductor by a one-dimensional finite chain of altering s orbital and p orbital. The energy states and their intensities are calculated for different n (n is the number of the layers of semiconductor film). The results are compared with those of a semi-infinite crystal.
