Simulation studies for surfaces and materials strength

Abstract

During this period investigations were carried out in three areas. Optimum energies and structures were estimated for single step ledges formed in the (111) surface of diamond. Binding energies of carbon atoms adsorbed on a (2x1) reconstructed Si(100) surface were calculated as a function of sub-monolayer coverages. Calculations were conducted to analyze the strain dependence of the binding energy of a carbon atom deposited on a (2x1) dimerized Si(100) surface. Results are discussed.
