Abstract

Empirical formulae are presented relating the dielectric constants of cubic semiconductors with the average atomic number of the constituent atoms. The inverses of the constants are found to be linearly related to the average atomic number with a square foot mean percentage error of less than 0.25% for elemental semiconductors, 1.3% for gallium and indium compounds, 3.4% for aluminium compounds, 1.4% for II-VI compounds, and 1.2% for lead compounds. Usefulness of the formulae is also illustrated for identifying incorrect values and for estimating unknown values.
