Empirical Pseudopotential Method (EPM) is used to calculate the energy gap of Si which is found to be indirect. Features such as refractive index, optical dielectric constant, bulk modulus, elastic constants and short-range force constants have been investigated. In addition to the shear modulus, Young's modulus, Poisson's ratio and Lame's constants for both bulk Si (p = 0%) and Porous silicon (PS) are derived. The calculated results are found to be in good agreement with other experimental and theoretical ones. Also, the Debye temperature of PS is estimated from the average sound velocity. To our knowledge, the optical properties using specific models and elasticity of PS are reported for the first time. 2011-07-20T07:42:19Z 2011-07-20T07:42:19Z 2011-08 Article Materials and Design, Vol. 32(7), August 2011, pages 4088-4093 0261-3069 http://www.elsevier.com/wps/find/homepage.cws_home http://www.sciencedirect.com/science/article/pii/S026130691100166X http://hdl.handle.net/123456789/13269 en Elsevier Ltd.
