Abstract:Polycrystalline thin films are widely used in the electronics industry and in surface protection applications. For most cases, a single crystal film would be preferable but is too costly or simply impossible to achieve. Thus, the grain boundaries are regarded as a necessary evil. We discuss the behavior of grain boundaries during film formation, processing and utilization, illustrating beneficial as well as deleterious effects. Some potential strategies for the control of grain boundary behavior are derived by… Show more
