摘要
Abstract The interrelations between the energy band gap and high frequency refractive index are summarized. The Penn model for the dielectric constant of semiconductors is used to construct a general interrelation, which avoids the shortcomings of the presently used relations. It is shown that the new relation with a characteristic set of constants for each alloy systems, Pb x Sn 1− x TE, Pb x Sn 1− x Se and Cd x Hg 1− x Te, describes the variation of high frequency refractive index with the energy band gap satisfactorily over the entire range of alloy compositions.
