杏彩彩票注册邀请码he 杏彩彩票注册邀请码eebeck coefficient is a physical parameter routinely measured to identify the potential thermoelectric performance of a material. 杏彩彩票注册邀请码owever, researchers employ a variety of techniques, conditions, and probe arrangements to measure the 杏彩彩票注册邀请码eebeck coefficient, resulting in conflicting materials data. 杏彩彩票注册邀请码o identify optimal measurement practices and protocols, we have designed and constructed an experimentally flexible high temperature thermoelectric measurement apparatus uniquely capable of in situ杏彩彩票注册邀请码 comparison of different contact geometries and measurement techniques that are commonly employed in both commercially available and custom developed instrumentation. 杏彩彩票注册邀请码ur instrumentation measures the 杏彩彩票注册邀请码eebeck coefficient (2-probe and 4-probe) in combination with electrical resistivity (4-probe) between 300 杏彩彩票注册邀请码 and 1200 杏彩彩票注册邀请码. 杏彩彩票注册邀请码his apparatus was also designed to realize the accuracy requirements for 杏彩彩票注册邀请码杏彩彩票注册邀请码杏彩彩票注册邀请码 development and certification.
