论文摘要
霍尔散射因子是使用RODE的迭代方法制定的,以求解Boltzmann传输方程,以使其在AB-Inito计算范围内很容易计算。使用此方法与基于密度功能理论的计算结合使用,我们证明了掺杂电子的TI2CO2中的霍尔散射因子随温度和浓度而变化很大,弱磁场的范围从0.2到1.3左右。电气传输主要使用三种散射机制进行建模:压电散射,声学散射和极性光子声子。即使该材料中的迁移率主要受声音子的限制,但压电散射也起着重要的作用,并未突出显示。
The Hall scattering factor is formulated using Rode's iterative approach to solving the Boltzmann transport equation in such a way that it may be easily computed within the scope of ab-inito calculations. Using this method in conjunction with density functional theory based calculations, we demonstrate that the Hall scattering factor in electron-doped Ti2CO2 varies greatly with temperature and concentration, ranging from 0.2 to around 1.3 for weak magnetic fields. The electrical transport was modelled primarily using three scattering mechanisms: piezoelectric scattering, acoustic scattering, and polar optical phonons. Even though the mobility in this material is primarily limited by acoustic phonons, piezoelectric scattering also plays an important role which was not highlighted earlier.
