Defect Structure and Processes

Our research involves "computer experiments" using classical and quantum mechanical methodologies of the structure and properties of crystalline defects.

Most of the calculations are carried out at the Cambridge-Cranfield High Performance Computing Facility (CCHPCF), the CRAY T3E parallel supercomputer based at Manchester (CSAR) and the HPCx facility at Daresbury.
