Electronic Structure of BP Studied by Resonant Soft X-ray Emission Spectroscopy

Abstract

The B1s and P2p soft x-ray emission of BP has been measured using monochromatic synchrotron radiation as an excitation source. The band-gap energy was estimated to be about 2.1 eV which is in good agreement with other experiments. The emission bands which reflect the partial density of states in the valence band showed resonant aspects. The spectral profile was interpreted by a momentum conservation approach.
