Most physical and chemical properties of matter change, often quite drastically, when the system size is made smaller than 10-100 nm. We are interested in studying the nature and mechanism of various types of finite size effects in nanostructured solids. Our current research involves:

  • Size effects in superconductors, ferroelectrics and ferromagnets
  • Size-induced stabilization of novel crystal structures
  • One-dimensional Nanomaterials (Nanorods, Nanotubes)
  • Nano-nano composite structures
  • Novel applications of Nanomaterials
  • Raman Spectroscopy of nanostructured materials
  • High Resolution Electron Microscopy


  • Laser-induced x-ray and ion emission from nanostructured surfaces
  • Local properties of nanoparticles by Perturbed Angular Correlation
  • Formation, stability and reactivity of atomic clusters

Past Research

  • Optoelectronic properties (photoluminescence, photoconductivity and non-linear optics) of nanocrystalline semiconductors
