项目摘要
In this study, we demonstrate the efficiency as thermoelectric materials of off-stoichiometric oxide semiconductor in terms of electric and thermal conductivity. We succeed to obtain the value of dimensionless figure of merit to be 0. 3 in off-stoichiometric titanium oxide, that is quite large for ubiquitous oxides. The large value is due to a strong phonon scattering at crystallographic shear structure which is largely introduced by a thermal treatment.
在这项研究中,我们证明了非化学计量氧化物半导体作为热电材料在电导率和导热率方面的效率。我们成功地获得了非化学计量氧化钛的无量纲品质因数为 0. 3,这对于普遍存在的氧化物来说是相当大的。大值是由于晶体剪切结构处的强声子散射,这主要是由热处理引入的。
