热电关联材料与器件研究室

 

研究背景:

 

热电转换涉及电子和声子两种能量载体的交叉耦合响应效应。

 

温度场下的电响应现象被称为Seebeck效应,由德国科学家Thomas J. Seebeck在1823年发现,该效应可被应用于温差发电。电驱动下热流现象被称为Peltier效应,由法国科学家Jean C.A. Peltier在1834年发现,该效应可被应用于固态制冷。

 

尽管Seebeck和Peltier都成功地展示了热电器件的分别作为温差发电和固态制冷的潜在商业价值,他们都未能对热电输运现象给出正确的微观解释。19世纪是电与磁的时代,虽然在1856年开尔文勋爵成功地找出了Seebeck和Peltier效应之间的联系,并提出了第三个热电效应(Thomson效应),但仍未能唤起主流科学家们的关注。

 

20世纪中叶,随着人们对太空和未知地域科考的渴望,人们开始寻求一种不受环境、地域、天气的限制的持续能源。以同位素衰变产生热再由热电效应将热转换为电的子能电池概念被提出,热电转换器件和热电材料的相关研究才开始真正获得人们的关注,新型的窄带半导体热电材料Bi2Te3, PbTe, GeSi被相继发现。与此同时,热电器件在半导体制冷以及太阳能发电领域应用也获得了一些关注。其中基于Bi2Te3固态制冷器件获得商业化量产。然而由于转换效率太低,热电材料与器件的研究很快淡出人们的视线。

 

热电材料研究的真正春天源于上世纪90年代,由于石油价格的上涨引发对化石能源枯竭的担忧,人们因此开始探索开源节能的新技术。热电材料因为其在太阳能和废热发电应用潜在价值,而成为新能源技术的重要研究领域。在过去的20年热电材料在材料体系,制备工艺,纳米结构,能带结构等方法均获得前所未有的突破。然后由于器件层次的可靠接触界面瓶颈技术使得大部分的热电材料仍停留于在实验室。未来热电转换技术的研究需要人们从材料、器件、系统三个层次协调考虑效率、效能、以及可靠性要求。

 

研究内容:

 

1). 理论基础

研究实空间下电子和声子的量子输运现象以及与光、磁、力的关联耦合行为

2). 材料层次

4). 系统层次
