Threshold<i>K</i>-<i>LL</i>Auger spectra of P in InP

Abstract

The evolution of K-${\mathit{L}}_{2,3}$${\mathit{L}}_{2,3}$ $^{1}$${\mathit{D}}_{2}$ radiationless resonant Raman scattering into Auger-electron emission was studied by tuning synchrotron radiation across the K edge of P in InP. The spectrum can be interpreted in terms of a two-component model that involves excitation of a photoelectron (1) into a discrete excitonlike state and (2) into the continuum; extra-atomic relaxation is taken into account. Auxiliary studies of above-threshold Auger and photoelectron spectra arising from K photoionization were used to identify the dominantly atomic features of these spectra.
