Trends of combinations of elastic constants of covalent semiconductors with mean interelectronic separation

摘要

Motivated by the jellium model, which is most appropriate for simple sp electron metals, in which trends of elastic constants with interelectronic separation r(s) are the focus, some extrapolation is made to the covalent diamond-structure semiconductors. This leads to the exposing of interrelationships involving experimental elastic compliance data, for C, Si, Ge and alpha-Sn. [References: 18]
