报告摘要：
New materials enable new technologies. Thus, there is the ongoing need to discover materials with novel and improved function. Here, I discuss using theory combined with crystal chemical concepts to find new functional materials. An advantage of first principles approaches, such as those based on density functional theory, is the microscopic, atomic level view and the ability to test concepts using notional materials and constraints. This leads to understanding that can be used to find new mechanisms for producing desired functional behavior, as well as opportunities for cross-fertilization in the sense of using concepts from one class of functional materials to advance a different class. This cross-fertilization enabled by first principles methods is particularly powerful. I illustrate this here by examples, including unexpected connections between oxide ferroelectrics, thermoelectrics, phase change materials, semiconductors and other examples.
