Interacting donors inn-type GaP studied with Raman scattering and ESR techniques

Abstract
Raman scattering and electron-spin-resonance (ESR) experiments have been performed on the same set of sulfur- and tellurium-doped gallium phosphide samples having various dopant concentrations. Impurity-related features of both Raman and ESR spectra indicate the presence of interactions between donors. The analysis of the data shows that these interactions are detected by Raman spectroscopy at a value of the mean distance between impurities significantly lower than that detected by the ESR technique.
