Current Research

  • Application of ion beam based techniques to a wide range of problems in materials science and solid state physics.

  • Development of Nuclear Microscopy and the various analytical and lithographic techniques associated with it, eg ERDA, IBIC, RBS, Proton Beam Writing.

  • Proton beam writing, a true 3D micromachining process that was invented and developed at the Centre for Ion Beam Applications (CIBA) at the physics department, NUS, Singapore.

  • Development and applications of high resolution (magnet spectrometer) RBS and ERD, a quantitative technique for the analysis of ultrathin film systems.
