Correlations between the cohesive energy and a crystallographic ratio in group‐II chalcogenides

Abstract

Correlations between the cohesive energy per mole and a crystallographic ratio in group11 chalcogenides are presented. It is shown that the linear combination of the anion radius and the nearestneighbour distance is a constant in these materials. Results obtained agree with works reported earlier. This work highlights the significance of the anion radius in determining the cohesive energy in group11 chalcogenides.

Systematic Variation between Cohesive Energy and a Lattice Ratio in Alkali Chalcogenide Crystals

“…Values of the relevant quantities are given in Tables 1 and 2 genides [9] and alkali halides [10]. The group-II chalcogenides and alkali halides generally crystallize in the NaCl structure with a coordination number of six.…”
