    Research Interests

    • Mechanistic studies of fast heavy ion induced desorption (i.e. electronic sputtering) of solids: (i) Measurements of the structural parameters of the radiation damage tracks on insulating surfaces, using Atomic Force Microscopy (AFM)- a novel near- field scanning probe technique having atomic resolution. (ii) Characterization of photons emitted from organic (especially biomolecules) and inorganic compounds due to fast heavy ion impact.
    • Mass spectrometry applications of fast heavy ion/photon induced desorption: (i) Development of plasma desorption mass spectrometry (PDMS) and Matrix Assisted Laser Desorption/Ionisation (MALDI) mass spectrometry facilities at the Department of Physics of the University of Colombo. (ii) The application of PDMS to natural product compounds isolated from medicinal plants & Organic metal complexes.
    • Physics education
    • Graphene-based applications
