Simulation of nanoscale patterns yielded by ion bombardment of solid surfaces
This thesis includes numerical investigations into two topics of self-organized topographies produced on solid surfaces that are bombarded with a broad ion beam. The first topic is the formation of terraces. When a surface is bombarded at relatively large angles of incidence, the surface often develops facets that are characterized by large regions of nearly constant gradient in height, which are called terraces. The second topic is related to the observation that when the surface of a nominally flat binary material is bombarded with a broad, normally-incident ion beam, disordered hexagonal ...
