摘要：

A theory is presented to describe the absorption spectrum of amorphous semiconductors in the presence of an external electric field. Besides isotropic third-derivative EA signal, the theory reveals an appearance of polarization dependent anisotropic EA signal characteristic to disordered media. Comparing the theoretical and experimental results on the EA effects as well as average dipole-matrix element produces comprehensive evaluations of various band-edge parameters including mean free path.
