Antiperovskite Interfaces for Materials Design (Award #1629270)
Materials with the perovskite crystalline arrangement of atoms have played important roles in applications ranging from electronic and magnetic devices to micro-machined actuators and sensors. Some of the most interesting phenomena arise at interfaces between these and other materials, where the atomic and structural aspects combine to form new materials in their own right. The main goal of this research is the discovery of a new class of interface materials based on antiperovskites. These antiperovskites invert the atomic positions in the perovskites, creating unique, wide-ranging properties different from previous materials. Interfaces between these two “anti”-structures create unexplored fundamental opportunities for materials design. This research will discover the fundamental principles controlling these new materials systems, develop atomic-scale design principles, and create and explore these interfaces for potential applications in electronic, magnetic, and quantum-controlled devices.
