We study point defects in solids with atom-scale resolution. Principal systems under study are intermetallic compounds having the CsCl structure such as NiAl. Outcomes include identification of high-temperature equilibrium defects and of defects produced by plastic deformation, measurement of defect concentrations, and determination of formation, migration and binding energies.
Current research is on equilibrium defect properties and site preferences of dilute solutes.
