Thermoelectric Properties Measurement System

热电材料作为绿色能源范例的一个关键要素得到了深入研究;它们可以从太阳能或废热发电，也可以用于固态制冷，热电材料的研究预计将大大有助于加拿大未来的经济活动。该领域的许多研究工作都致力于提高热电品质因数zT，这需要同时测量热导率、塞贝克系数和电导率。因此，测量zT作为温度的函数是热电研究中必不可少的一步。我们建议获得一个热电性能测量系统，并将此功能添加到现有的量子设计物理性能测量系统（PPMS）。该系统将使我们能够获得宽温度范围（2K-400 K）的热电优值，并支持开发低温和纳米织构热电材料的研究活动。该系统将成为支持NSERC CREATE计划的主要实验设施之一，该计划名为“驯服损失的热量：热电培训和研究”。"

Thermoelectric materials are intensively studied as a key element of the green energy paradigm; they can generate electricity from solar or waste heat, and can also be used for solid-state refrigeration, and thermoelectric materials research is expected to contribute significantly to the future economic activity of Canada. Many of the research efforts in the field are devoted to improving the thermoelectric figure of merit, zT, which requires simultaneous measurements of thermal conductivity, the Seebeck coefficient, and electrical conductivity. Therefore, measuring zT as a function of temperature is an indispensable step in thermoelectrics research. We propose to acquire a thermoelectric properties measurement system, and add this capability to the existing Quantum Design Physical Properties Measurement System (PPMS). This system will allow us to obtain the thermoelectric figure of merit over a wide range of temperatures (2K-400K), and support research activities in developing low-temperature and nano-textured thermoelectric materials. This system will be one of the main experimental facilities supporting the NSERC CREATE program entitled "Taming the Lost Heat: Training and Research in Thermoelectrics."
