Optical characteristic and gap states distribution of amorphous SnO₂:(Zn,In) film

In this paper the fabrication technique of amorphous SnO₂:(Zn,In) film is presented. The transmittance and gap-states distribution of the film are given. The experimental results of gap-states distribution are compared with the calculated results by using the facts of short range order and lattice vacancy defect of the gap states theory. The distribution of gap state has been proved to be discontinuous due to the short-range order of amorphous structure.
