摘要：

A simple one-dimensional model of a diatomic chain is used to explain the unusually large values of the transverse effective charge (ZT*) in cubic IV-VI compounds. By using a pseudopotential formalism, the authors have related ZT* to the chemical electronegativity and found good agreement with experiment in both the magnitude of ZT* and in its trend along the series.
