项目摘要

The main thrust of my research is into materials for the thermoelectric power generation, a unique technique to generate electricity from, e.g., waste heat. Thermoelectric power generation is foreseen to play an increasing role in the near future, considering the pressing need for alternative energies due to declining natural resources. Increasing the efficiency of thermoelectric materials would further accelerate this development, which may be achieved discovering new materials as well as by improving established materials via nanostructuring or band structure engineering, for example.**** One focus is on our ongoing efforts to enhance the thermoelectric properties of AyMo3Sb7xTex and isostructural materials by substitution chemistry and nanostructuring, which were discovered and characterized in our group supported by previous NSERC Discovery Grants. A second focus is on a new class of thermoelectrics based on copper chalcogenides, discovered during the tenure of my current NSERC Discovery Grant. This basically unexplored class exhibits exceptional promise, as evident from the thermoelectric performance of the Cu2Se, if the stability can be improved, which will be the objective of this research proposed here. Third, we will pursue new ideas in the area of thermoelectric thallium tellurides, after our recent breakthrough in this area stemming from the current Discovery Grant. Fourth, we will commence studies into transverse thermoelectrics, a novel concept relying on the p- and n-type carriers moving orthogonal to each other. This basic, exploratory research will constitute a completely new focus of my Discovery Grant. **** Overall this will contribute to the education and training of eight graduate students, as well as several undergraduate students. These HQP will receive an extensive practical and theoretical background in general materials chemistry focusing on energy conversion/generation, matters of vital interest to Canada.**

我的研究的主要目的是投入热电发电的材料，这是一种独特的技术，可从浪费热量产生电力。考虑到由于自然资源的下降，热电发电在不久的将来可以在不久的将来发挥越来越多的作用。例如，提高热电材料的效率将进一步加速这一发展，例如，通过纳米结构或带结构工程来提高建立材料以及改善已建立的材料。 NSERC DISCOVER GRANTS。第二个重点是在我当前的NSERC发现赠款任期内发现的基于铜硫化剂的新型热电学。如果可以提高稳定性，这将是CU2SE的热电性能的证据，这基本上具有出色的阶级，作为来自CU2SE的热电性能的证据，这将是本研究的目的。第三，在我们最近在目前的发现赠款中突破这一领域的突破之后，我们将在热电tollium tellurides领域中追求新的想法。第四，我们将开始研究横向热电学，这是一个新的概念，依靠P-和N型载体相互将正交移动。这项基本的探索性研究将构成我发现赠款的全新重点。总的来说，这将有助于八位研究生以及几位本科生的教育和培训。这些HQP将在一般材料化学中获得广泛的实用和理论背景，重点是能量转化/发电，加拿大至关重要的问题。**
