摘要

The theory of infrared 45 degrees reflectometry is revised and generalized to the case of anisotropic very-thin films and heterostructures on substrate. We obtain approximate expressions for the difference Delta(45) = R-p - R-s(2) between the reflectivity for p-polarized light (R-p) and the squared reflectivity for s-polarized light (R-s(2)) at 45 degrees angle of incidence. These results give a good interpretation of frequency spectra of Delta(45) and allow to associate correctly the resonances in Delta(45) With transverse and longitudinal optical phonons in anisotropic films. The application of the infrared 45 degrees renectometry to superlattices is discussed. [References: 36]
