Cohesive energy of zincblende (A$^{III}$ B$^{V}$ and A$^{II}$B$^{VI}$) structured solids

摘要

In this paper we present an expression relating the cohesive energy (e???coh in kcal/mol) of A$^{III}$B$^{V}$ and A$^{II}$ B$^{VI}$ semiconductors with the product of ionic charges ($Z_{1}Z_{2}$) and nearest-neighbour distance d (?…). The cohesive energy values of these solids exhibit a linear relationship when plotted on a loga€“log scale against the nearest-neighbour distance e?‘‘(?…), but fall on different straight lines according to the ionic charge product of the solids. A good agreement has been found between the experimental and calculated values of the cohesive energy of A$^{III}$B$^{V}$ and A$^{II}$B$^{VI}$ semiconductors.
