Epitaxial antiperovskite/perovskite heterostructures for materials design
Engineered heterostructures or layered materials made with complex oxide materials are a rich source of emergent technical phenomena and applications. Materials scientists aim to develop new materials functionalities by interfacing oxide perovskites with substrates containing dissimilar crystallographic properties, in a vastly unexplored avenue. In a new report, Camilo X. Quintela and an international group in materials science, physics and engineering in the U.S., Norway, China and South Korea proposed an unprecedented direction for materials design based on nitride antiperovskite and oxide perovskite crystals. In this work, they successfully layered two crystalline materials known as perovskites and antiperovskites together, to create an interface with unique electrical properties for applications in a new class of quantum materials.
