Prediction of Fermi energies and photoelectric thresholds based on electronegativity concepts

View publication

Abstract

A simple formula involving the geometric mean of the electronegativities of the two components is proposed for the determination of the Fermi energies and hence the photoelectric thresholds of simple binary compounds, and is found to be surprisingly accurate for all presently available data. A theoretical basis for the use of the "postulate of the geometric mean" is also given. © 1974 The American Physical Society.
