Research Interests Computaional Chemistry: Energetics,stability and magnetic properties of heterogeneous transition metal clusters Experimental Solid state Chemistry: Semiconductor materials and their applications in solar energy conversion and gas sensing Professonal Background B.Sc. Special Degre in Chemistry, University of Ruhuna, Sri Lanka(1994), Ph.D. in Computational Chemistry, University of Maine, USA(2002) . The Best Teaching Assistant in general Chemistry in 2002, University of Maine, USA Research Synopsis Our group works in both areas of theoretical research(computational research) and experimental research. * Computational studies of transition metal clusters We use the molecular dynamics simulation technique and Quantum mechanical calculations to find the most stable structures of neat and heterogeneous transition metal clusters in nano-size.Melting points and other thermodynamics properties are determined by using multiple histogram method integrated to MD programs. We use our own FOTRAN codes in our simulation. We compare classical results with quantum results. This project is a collaborative work with Professor Francois Amar, Department of Chemistry, University of Maine,USA and use University of Maine computer facilities to run Gaussian 03 package in Quantum calculation * Semicounductor thin films We focus on preparation and chareterizayion of semiconductor thin films for solar energy conversion and for gas sensing. We develops simple and econmical laborotary methods in preparation of thin films and main features of these methods are the purity of oxides and close band gap energies to the standard values |
