Optical Polarization and Crystal Epitaxy Effects

The problem, in essence, is to provide for an angular interaction by an accurate quantum mechanical description of the transition matrix for absorbance and reflectance. In other words, the field of the electromagnetic wave which penetrates the bulk metal will determine the photocurrent, provided that a correction is made for the reflected light. It has been shown that, approximately,  

Subsequently, objections to this model were raised by Gurevich et who questioned the validity of inserting matrix elements of the type given in Eq. (34) into macroscopic (classical) formulas. An alternative physical model accounts for the real part of the permittivity of the metal becoming zero near to the surface. At this point, the field strength exhibits a sharp maximum and the functional dependence of the photocurrent becomes 

Obviously, a more comprehensive treatment is needed for crystalline materials. In addition, experimental studies interpreted using this type of analysis have revealed that surface contributions must be included to supplement the bulk effects.

A particularly helpful discussion of what they call the vectorial photoeffect by polarized light has been given by Sass and Gerischer/ The optical transition matrix element, in restricted form, is given by three terms
