Research Abstract

Characteristics of the bandpass-type photon detector for inverse-photoemission spectroscopy has been significantly improved not only with respect to the full width at half maximum, but also in terms of the sensitivity. The new detector has a full width at half maximum of 0.36 eV and the sensitivity is improved by a foctor of 1.6.
The overall energy resolution of the inverse-photoemission spectrometer consisting of an electron gun with a BaO cathode and the new detector has been estimated to be 0.44 eV using polycrystalline gold, which is assumed to have a step-like density of states near the Fermi level.
The newly developed detector in the present study has been successfully used in studies of unoccupied electronic states in diluted magnetic semiconductors, amorphous semiconductors and magnetic materials.
