主要研究方向：

先进固态制冷技术研发与应用

热电材料是一类能实现热能和电能相互直接转换的功能材料，作为一种清洁能源技术，基于其制备的发电（Seebeck效应）或制冷（Peltier效应）模块具有无机械运动部分、无化学反应、静音、安全、稳定、寿命长等特点，在深太空探测器自供电、废热回收利用、全固态制冷及热能管理等领域有着广泛的应用前景。我们的研究主要聚焦于先进功能热电材料的集成制备、输运表征、模块构筑及应用开发，针对制冷器件的极限温差和效率提升瓶颈，凝练关键科学技术问题，打造材料制备—物性测量—器件构筑—模块应用的全链条研究，目前研究课题包括但不限于：

（1）热电功能材料的制备及测量；

（2）固态制冷器件的构筑及应用；

（3）微型热电器件的芯片集成及应用。

过去的主要工作及获得的成果：

1. 将微机电加工工艺（MEMS）与电化学沉积手段（ECD）相结合，成功制备了具有高集成密度的微型热电制冷器件（micro-TECs），集成密度高达5500/cm²，并首次系统测量了微型热电制冷器件的长期服役性，和循环稳定性(1千万次以上)，所得器件数据为领域内领先，此工作被Nature Electronics杂志选为当期封面文章报道。
2. 利用应力调控自卷曲（strain-engineered self-rolling）的方法，发展了一种制备单晶/非晶（Si/SiOx）、半导体/金属（GaAs/Metal）、无机/有机（GaAs/Polymer）杂化超晶格的方法，并研究了各体系的热学传输特性，发现通过调控超晶格薄膜的界面特性可以很有效地降低材料的热导率。
3. 研究了低维电子体系，如：零维量子点（GaSb/GaAs Type II QDs）、一维纳米线（InAs， Bi₂Se₃）、二维电子气（GaAs/AlGaAs heterojuction）的电学和热学输运特征。

相关成果发表在Nature Electronics, Joule，Energy Environ. Sci., Adv. Mater., iScience, ACS Nano, Nano Letter, Appl. Phys. Lett.等国际学术期刊上。
