H., Huan SiGe alloy Optical properties VASP Alloys Materials engineering Semiconductor alloys Band structure engineering Link to publisher's homepage at www.elsevier.com Ultra-soft pseudopotential (US-PP) calculations with a powerful package called VASP (Vienna ab initio simulation package) are used. The total density of state and the energy gap of Si0.5Ge0.5 alloy of zinc-blende structure are calculated using the band structure scheme. The energy gap is found to be indirect for the zinc-blende structure. The results of refractive index and optical dielectric constant of Si0.5Ge0.5 alloy are investigated. The results are in reasonable agreement with experimental and theoretical ones. 2009-08-04T07:15:56Z 2009-08-04T07:15:56Z 2008-12 Article Solid State Communications, vol.148 (11-12), 2008, pages 521-524. 0038-1098 http://www.sciencedirect.com/science/journal/00381098 http://hdl.handle.net/123456789/6671 en Elsevier Ltd |
