A study of energy gap, refractive index and electronic polarizability of ternary chalcopyrite semiconductors

A simple relation between the optical electronegativity، energy gap، refractive index and electronic polarizability is given for ternary chalcopyrite semiconductors. Energy gap has been evaluated from the optical electronegativity whereas refractive index and electronic polarizability values have been evaluated from the energy gap by proposing a linear relation between them. The calculated values are in fair agreement with the experimental values and earlier researchers. This work highlights the significance of interrelation between these parameters.
