Abstract Scope |
Interfaces in crystalline solids are invariably decorated by line defects—both dislocations and disconnections—which influence the stability and mobility of the interfaces. However, our ability to predict what line defects are present at interfaces and how interactions among these line defects affect interfacial properties is lacking. We present two recent advances in theory and modeling of line defects at interfaces which enable new insights. First, we present a new methodology for enumerating all possible line defect structures at interfaces based on the Frank-Bilby equation. Using this methodology, a “menu” of the most favorable structures can obtained and analyzed. And secondly, we present a new technique called interfacial line defect analysis (ILDA) which automatically identifies and extracts interfacial line defects in atomistic datasets without requiring any user input on the nature of the interface. |
