Research

Overview

Research Group: Condensed Matter Physics

The research in my group is focused on understanding the correlation between structure and functionality of advanced nano-materials and bimolecular complexes on the atomic and molecular level. The atomic structure of either artificial nanoscale materials or molecular bio-machines or is the key factor that determines their functionality. Hence determining this correlation is one of the fundamental goals of nanoscience and technology. In my research over the last 15 years I have used both experimental (e.g advanced atomic resolution electron microscopy and thin film growth) and theoretical techniques (first principle quantum mechanical calculations) to elucidate this connection.

Research Interest

  • Half-metals for spintronic applications
  • Polar Oxides for electronic applications and catalysis
  • 3D Topological Insulators: thin films and heterostructure
  • Advanced electron microscopy methods for atomic level materials characterisation
