Creation of Surface and Bulk Defects of Germanium and Surface Roughening of Germanium During High Energy Ion Irradiation
Abstract
dc:descriptionSurface patterns of valleys and mounds are observed at 250°C and 275°C due to the asymmetric kinetics of surface vacancies at step edges, while no surface pattern formation is observed at room temperature. Also, model of Politi and Villain agrees relatively well with the roughening and coarsening of the Ge(111) surfaces etched by 5 keV Xe ions at 250°C and 275°C. At 300°C, a surface pattern is observed only when the incident ion direction is parallel to the step direction; this surface pattern is the ripple morphology produced by curvature dependent sputtering yield.
