Investigated optical studies of Si quantum dot
(Elsevier Ltd., 2011-09)
Further study of the quantum dot potential for Si is presented. This potential has been calculated by means of our recent empirical model. The indirect energy gap (Γ-X) is calculated using the full potential-linearized ...
Optical investigations using ultra-soft pseudopotential calculations of Si0.5Ge0.5 alloy
(Elsevier Ltd, 2008-12)
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 ...
Calculated optical properties of GaX (X=P, As, Sb) under hydrostatic pressure
(Springer-Verlag, 2011)
The hydrostatic pressure dependence of the principal energy gaps and of the optical properties of GaX (X = P, As and Sb) has been calculated using the full potential-linearized augmented plane wave (FP-LAPW) method. The ...
