Waste heat, which is discharged into the environment from industrial plants and vehicle exhausts, represents a huge amount of lost energy and is a major contributor to global warming. Thermoelectric materials, which can generate electricity from the waste heat, could play an important role in a global sustainable energy solution while reducing greenhouse emissions. This program is aimed at experimental and theoretical development of new concepts to engineer the interfaces with various atomic stacking sequence of two complex oxides and also the three-dimensional binary nanocube superlattices to enhance the energy conversion efficiency of oxide based thermoelectric materials by several times over today's state-of-the-art.

工厂和汽车尾气排放到环境中的废热代表着大量的能源损失，是全球变暖的主要原因。热电材料可以利用废热发电，可以在全球可持续能源解决方案中发挥重要作用，同时减少温室气体排放。该项目旨在实验和理论开发新概念，以设计两种复杂氧化物的各种原子堆叠序列以及三维二元纳米立方体超晶格的界面，以将氧化物基热电材料的能量转换效率提高几倍于当今最先进的技术。
