Debye temperature and melting point of ternary chalcopyrite semiconductors

Debye temperature (θD)(θD) and melting point (Tm)(Tm) of AIBIIIC2V I and AIIBIVC2V chalcopyrite semiconductors have been discussed. Four simple relations have been proposed to calculate the values of θDθD. Two are based on plasmon energy data and one each on TmTm and molecular weight (WW). We have also proposed two simple relations to calculate TmTm of these semiconductors. One is based on plasmon energy and the other on W. The calculated values of θDθD and TmTm from all equations are compared with the experimental values and the values reported by different workers. Reasonably good agreement has been obtained between them.
