Beyond Phononic Crystals-Building New Concepts to Enhance Thermoelectricity

废热从工业工厂和汽车尾气排放到环境中，代表着巨大的能量损失，是全球变暖的主要原因。热电材料可以利用余热发电，在减少温室气体排放的同时，可以在全球可持续能源解决方案中发挥重要作用。该计划旨在实验和理论开发新的概念，以设计具有不同原子堆积顺序的两个复合氧化物和三维二元纳米立方体超晶格的界面，以提高氧化物基热电材料的能量转换效率，使其比当今最先进的水平提高几倍。

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.
