Defects and Interfaces

Overview

Many interesting material properties are based on microscopic defects and chemical interfaces, such as dopants and grain boundaries. For example, dislocations are inhibited by the presence of grain boundaries and prior dislocations, causing improved mechanical strength. By observing these small features, one can determine how they impact material properties.
