Abstract

Interatomic force constants of A IIB VI and A IIIB V semiconductors have been calculated using plasma oscillations theory of solids. Two simple equations relating the bond-stretching force constant ( α) and plasmon energy have been proposed. The calculated values of α have been used in calculating the values of bond-bending force constant ( β). Our calculated values of α and β are in excellent agreement with the values reported by different workers.
