Abstract
The refractive indices of In0.53Al0.16Ga0.31As and In0.53 Al0.21Ga0.26As/InP were measured for the first time in the wavelength range from 280 to 1900 nm by spectroscopic ellipsometry. The results on InP and GaAs are in good agreement with the measurements in the literature. The interface layer due to the exchange of phosphorus and arsenic atoms during the desorption procedure of the molecular beam epitaxy growth exists and was also found by high resolution X-ray diffraction
