Beyond Phononic Crystals-Building New Concepts to Enhance Thermoelectricity

从工业工厂和汽车尾气排放到环境中的废热代表了大量的能量损失，是全球变暖的主要原因。热电材料可以从废热中发电，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。该计划旨在实验和理论发展新概念，以工程师的接口与两个复杂的氧化物的各种原子堆叠顺序，也是三维二元纳米立方体超晶格，以提高基于氧化物的热电材料的能量转换效率几倍于今天的最先进的。

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.
