Professor of Physics

Research Interests:

• Investigation of surfaces by nuclear phenomena
  
  
Crystalline surfaces and two-dimensional clusters are investigated through the recoil of nuclei undergoing weak decay and scattering off their immediate atomic neighborhood. The work involves the preparation of suitable isotopes, their deposition on the surfaces in ultrahigh vacuum systems, and conducting the measurements. This is done in conjunction with theoretical analysis that relates it to the substrate-adsorbate interaction. 


• Thickness measurement and thin film characterization by alpha particle energy loss
  
  
Applications of the nuclear phenomenology of alpha-particle energy loss include thickness
measurements in real time in MBE and MOCVD systems, and investigations of complex
three-dimensional structures following growth.


• Molecular dynamics calculations 
  
  
Intensive molecular dynamics calculations are carried out for both metallic and complex (metal-oxide) systems. The calculations are carried out on parallel computers and apply specially developed algorithms. Among other problems, the macroscopic formation of faults in matter are investigated.
