Refractive Index and Electronic Polarizability of Ternary Chalcopyrite Semiconductors

Simple models are proposed for the calculation of refractive index n and electronic polarizability α of A^IB^IIIC₂^VI and A^IIB^IVC₂^V groups of chalcopyrite semiconductors from their energy gap data. The values of n and α for 2 compounds of A^IB^IIIC₂^VI family and 12 compounds of A^IIB^IVC₂^V family are calculated for the first time in this work. The proposed models are applicable for the whole range of energy gap materials. The calculated values are compared with the available experimental and reported values. A fairly good agreement between them is obtained.
