Perovskite materials are an excellent model system to study functional properties and processes. More importantly, a wide gamut of functional properties can be observed in this class of materials, governed by the chemical composition, spanning the range of insulators, semiconductors, ionic conductors, metals and magnets, among others. As crystals, these material classes can be combined into heterostructures using thin film techniques to unlock new functionalities leading to the next generation of electrical and electronic devices. By employing pulsed laser deposition, the chemistry of each material can be finely tuned, which can drastically alter the properties of the resultant material and heterostructure. In the Physical Properties of Materials Group in LMX, we explore the chemistry-structure-function relationships in perovskites, with a particular focus on oxides. Herein, the recent progress on ferroelectric, semiconducting and metallic materials will be discussed in the scope of computing applications. The crucial role stoichiometry plays in the final properties of a material, both in the film bulk and at the interfaces, will be described. Finally, the latest advancements in epitaxy within LMX will be outlined, with the goal of promoting interlaboratory collaborative efforts on materials discovery.
