density of states

density of states

The number of electronic states per unit volume and per unit energy in energy band. The density of states (DOS) of the conduction band can be investigated by high energy resolution EELS. (The energy resolution is better than 1 eV for a TEM equipped with a thermal FEG and is about 0.3 eV for that with a cold FEG.) The DOS of the valence band is obtained by XES, which analyzes X-rays emitted from a specimen by the illumination of the incident electron beam. An energy resolution better than 1 eV is required for the analysis of the valence band. A recently-developed WDS analyzer provides an energy resolution of about 0.5 eV, giving us good DOS of the valence band.
