Point Defects in Optical Solids

Point defects and impurities may create or enhance great optical phenomena in semiconductor or insulator solids, via creating localized states inside the band gap. Photo-luminescence, thermo-luminescence, and optically stimulated luminescence are beneficial examples of such optical phenomena.


Thermoelectric materials

Thermoelectric phenomena, which involve direct and mutual conversion of heat and electricity without any combustion or mechanical process, could play an important role in a global sustainable energy solution. However, low efficiency of the traditional thermoelectric materials has limited their usage in space based or other niche applications. Recently, nanoscale phenomena are successfully applied to develop thermoelectric materials with enhanced room temperature performance.


Novel magnetic materials

First-principles investigation of novel magnetic materials and structures is an active field in the developing area of Spintronics. Half-metallic Heusler alloys, ferromagnetic binary alloys, and p orbital magnetism are examples of novel magnetic systems.


Atomic nanoclusters

Atomic nanoclusters exhibit size dependent properties and hence are very interesting systems for designing devices with desired properties and applications. In spite of advanced and expensive experimental characterization techniques, developed for nanostructures, accurate understanding of these tiny systems is a challenging issue.
