My experience is amalgamation of surface science, material science and applied physics. The material from 0-Dimension to 3-Dimension were synthesized, processed and modified. The solid thin films and multilayers were grown in extremely clean environment through various high vacuum and ultra-high vacuum techniques. The surface topology, surface composition, and surface structure is analysed to identify and understand the surface problem. The surface analysis lead to solution of surface problem and surface could be modified accordingly. The main aim is to understand the surface problems and modify the material for industrial application. The 3-dimensional alloys are grown and characterized.  The analysis of physical properties are done to modify the alloy for industry friendly applications. Following are the expertise summarised:
