Guangzong Xing, Jifeng Sun, Khuong P. Ong, Xiaofeng Fan, Weitao Zheng, David J. Singh

摘要:

我们讨论并提出了搜索策略,寻找新的热电组合物的基础上第一性原理电子结构和运输计算。我们说明他们的应用程序寻找潜在的n型氧化物热电材料。这包括基于电子能量等值面的可视化的屏幕。我们报告的化合物,显示出潜在的热电材料以及详细的性能,包括SrTiO 3,这是一个已知的热电,适当掺杂KNbO 3和金红石TiO 2。

英文摘要:

We discuss and present search strategies for finding new thermoelectric compositions based on first principles electronic structure and transport calculations. We illustrate them by application to a search for potential n-type oxide thermoelectric materials. This includes a screen based on visualization of electronic energy isosurfaces. We report compounds that show potential as thermoelectric materials along with detailed properties, including SrTiO3, which is a known thermoelectric, and appropriately doped KNbO3 and rutile TiO2.
