A new subfield, inelastic thermoelectricity, is introduced where the elementary physical pictures and models are illustrated. We show several advantages of inelastic thermoelectricity: the potential for high-performance thermoelectricity and the anomalous transport effects that cannot be realized in elastic transport. We specially focus on several unusual effects: cooling by heating, linear thermal transistor effect, thermal control etc. Some recent studies on near-field thermoelectric effects are also presented. We further discuss phsyical problems extended from thermoelectric studies: universality of optimal efficiency and power, and stochastic efficiency fluctuations.

Rev. A/B/E, Optics Express等一流期刊上发表论文40多篇。曾发现半导体中载流子自旋弛豫的一系列普适性规律及其中多体散射机制的独特作用,并在Physics Reports上撰写半导体自旋耗散动力学的重要综述之一。首次与实验合作观测并解释了一维表面声子极化激元导致的近场光学效应及其物理性质。提出了光学系统实现室温玻色爱因斯坦凝聚的物理条件和实现方案,设计了一种新型多路并行光学生物传感器。作为早期的工作者之一,推动了介观非弹性热电输运领域的发展,在此方向开展了一系列的研究,并撰写了该领域第一篇综述论文。
