Optical properties of random alloys : a formulation
نویسندگان
چکیده
We present here a formulation for the calculation of the configuration averaged optical conductivity in random alloys. Our formulation is based on the Augmented Space Theorem introduced by one of us (Mookerjee,1973). We show that disorder scattering renormalizes the electron and hole propagators as well as the transition amplitude. We also study the effect of vertex corrections in a simplified ladder diagram approximation.

متن کاملSurface plasmon resonance of Au-Cu bimetallic nanoparticles predicted by a quasi-chemical model
Au-Cu alloys are functional materials with nonlinear optical applications. However, the optical properties of such alloys are difficult to predict due to the random mixing of materials. In this paper, we present a quasi-chemical model to simulate the optical properties of Au-Cu alloy systems based on the mixing of Gibbs free energy. This model is also able to predict the position of the surface...

The performance of components produced by conventional route of a thermo mechanical process and those produced by continuous casting is interesting from different aspects of economy and technology. The performance of products in their service depends on their properties which are strongly influenced by production routes. In the present work the hardness, tensile and tensile-impact behaviors of ...
متن کاملAn investigation on metallurgical and mechanical properties of vacuum brazed Ti-6Al-4V to 316L stainless steel using Zr-based filler metal
Both Ti-6Al-4V and 316L stainless steels are widely used as engineering alloys. Fusion welding of these two alloys is not easily possible due to their incomplete solubility in each other. Brazing is one of the best choices for joining dissimilar alloys. In this study, wettability experiments were done at 940 and 970 ºC for 5, 15 and 30 min. Also, joining of these two alloys was carried out at 9...
متن کاملOptical properties of perovskite alkaline earth titanates : a formulation
Abstract. In this communication we suggest a formulation of the optical conductivity as a convolution of an energy resolved joint density of states and an energy-frequency labelled transition rate. Our final aim is to develop a scheme based on the augmented space recursion for random systems. In order to gain confidence in our formulation, we apply the formulation to three alkaline earth titana...
