RELATIONSHIPS BETWEEN LATTICE ENERGY, INTERIONIC DISTANCE AND PLASMA ENERGY IN II-VI-GROUP SEMICONDUCTORS

Lattice energies have been evaluated from the interionic distances for II-VI group semiconducting compounds based on the assumption that a l inear relation exists between lattice energies and interionic distance s within a molecular group of compounds. A new linear relation has als o been proposed for the evaluation of plasma energy directly from the lattice energy values. The calculated plasma energy values are used in the estimation of electronic polarizability in II-VI group semiconduc ting compounds. Good agreement is observed between computed and litera ture values of electronic polarizability.
