Relationship between Refractive Index, Electronic Polarizavility, Optical Energy Gap Optical Electronegativity and Plasmon Energy in I-Iii-Vi2 and Ii-Iv-V2 Groups of Semi Conductors

Refractive index(n), Electronic Polarizability (αp), Optical Energy Gap(Eg) and optical electronegativity(Δχ* ), of I-III-VI2 and II-IV-V2 groups of ternary semiconductors have been calculated using Plasmon energy data on the basis best fit data, new relations have been proposed for the calculation of refractive index , electronic polarizability, optical energy gap and optical electronegativity. The calculated values of n, αp, Eg and (Δχ* ) from the new relations have been compared with the values reported by different researcher. An excellent agreement with calculated values and experimental values has been obtained.
