Andrew WEE Thye Shen

Professor of Physics
Dean of Science

• Research is in the multidisciplinary field of surface and nanoscale science, with primary interests in surface nanostructure formation. The work involves ‘bottom-up’ self-assembly methods in vacuo for the spontaneously formation nanoscale templates on surfaces. Latest work involves single molecule studies and molecular electronics devices.

• Other research interests include:
• Surface reconstructures studied by STM, IV-LEED and DFT calculations,
  
• Application of synchrotron radiation techniques to surfaces and nanostructures,
  
• Depth resolution studies in SIMS and ultrashallow profiling
  
• Ion beam modification and nano-patterning of surfaces,
  
• Carbon nanotubes and related nanomaterials for nanodevice applications.
  

• Prof Andrew serves on several international journal editorial boards:
  • Int. J. Nanoscience (Co-Managing Editor),
  • Surface & Interface Analysis (Regional Editor),
  • Surface Review and Letters (Editorial Board).
  • Current Nanoscience (Editorial Board).
