Debye temperature and melting point of ternary chalcopyrite semiconductors

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