Soft-x-ray fluorescence spectra of III-V phosphides BP,GaP, and InP
The valence band electronic structures of the III-V phosphides BP, GaP, and InP were investigated using soft x-ray fluorescence spectroscopy and compared with band structure calculations using full-potential linearized augmented plane wave method based on density functional theory. The P L{sub 2,3} spectra of these phosphorus compounds are reported and compared with the calculated (s+d)-local partial densities of states (LPDOS{close_quote}s). For BP, the B K spectrum is also reported. Generally good agreement is obtained between the spectra and calculated LPDOS{close_quote}s. Two other interesting results were found. The normally suppressed P L{sub 1} spectrum was observed in resonance with the B K spectrum of BP. Also, strong resonant inelastic x-ray scattering was observed at the Ga M{sub 2,3} edge associated with energy loss to local electronic excitations from the Ga d states, permitting the Ga d states to be accurately located with respect to other band features.
