Band structures divulge that this compound is a direct energy band gap semiconductor. The obtained energy band gap value using mBJ is larger than those obtained within LDA, GGA and EVGGA. There is a strong hybridization between Si-s and S-s/p, Si-p and Zn-s, Ag-s/p and Zn-s, and Ag-s and Ag-p states. The analysis of the site and momentum-projected densities shows that the bonding possesses covalent nature. The dielectric optical properties were also calculated and discussed in detail. 2014-07-07T04:33:47Z 2014-07-07T04:33:47Z 2013-11 Article Applied Physics A, volume 116 (1), 2014, pages 333-340 0947-8396 (print) 1432-0630 (online) http://dspace.unimap.edu.my:80/dspace/handle/123456789/36065 http://link.springer.com/article/10.1007%2Fs00339-013-8126-0 10.1007/s00339-013-8126-0 en Springer Berlin Heidelberg
