The lattice constant, bulk modulus, derivative of bulk modulus and energy gap vary with bismuth concentration nonlinearly. The present calculations show that the band gap decreases substantially with increasing bismuth concentration and that spinorbit coupling influences the nature of bonding at high Bi concentrations. 2014-01-14T13:09:57Z 2014-01-14T13:09:57Z 2012-02 Article Journal of Solid State Chemistry, vol. 186, 2012, pages 47-53 0022-4596 http://www.sciencedirect.com/science/article/pii/S0022459611006219 http://dspace.unimap.edu.my:80/dspace/handle/123456789/31193 en Elsevier Inc.
