AB-INITIO CALCULATIONS OF CDS, CDSE AND CDTE SURFACES

We very briefly address structural and electronic properties of nonpol ar (110) and (<10(1)over bar 0>) surfaces Cd compound semiconductors. All calculations have been carried out self-consistently within local density approximation employing separable norm-conserving pseudopotent ials. The electronic structure has been calculated including spin-orbi t coupling and self-interaction and relaxation corrections. Our ab-ini tio results are found to be in good agreement with experiment data. (C ) 1998 Elsevier Science B.V. All rights reserved.
