论文摘要
SC2CF2，SC2CO2和SC2C（OH）2的霍尔散射系数是通过求解Boltzmann传输方程来计算的。这与基于密度功能理论的计算结合进行。 SC2CF2，SC2CO2和SC2C（OH）2中的电运输是通过考虑弹性（声学和压电）和非弹性（极性光子声子）散射来建模的。极性光语音（POP）散射是这些MXENES中最重要的机制。我们观察到有一个载体浓度的窗口，其中大厅因子急剧起作用。 SC2CF2获得了不可思议的高价值2.49，而SC2CO2的价值非常小，大约为0.5，而SC2C（OH）2实现了所谓的理想值1。我们在本文中提出，这种Hall因子行为在MXENES中的表面群体识别领域具有很大的希望，这是一个长期困扰研究人员的问题。
The Hall scattering factor of Sc2CF2, Sc2CO2 and Sc2C(OH)2 is calculated using Rode's iterative approach by solving the Boltzmann transport equation. This is carried out in conjunction with calculations based on density functional theory. The electrical transport in Sc2CF2, Sc2CO2, and Sc2C(OH)2 is modelled by accounting for both elastic (acoustic and piezoelectric) and inelastic (polar optical phonon) scattering. Polar optical phonon (POP) scattering is the most significant mechanism in these MXenes. We observe that there is a window of carrier concentration where Hall factor acts dramatically; Sc2CF2 obtains an incredible high value of 2.49 while Sc2CO2 achieves a very small value of approximately 0.5, and Sc2C(OH)2 achieves the so called ideal value of 1. We propose in this paper that such Hall factor behaviour has significant promise in the field of surface group identification in MXenes, an issue that has long baffled researchers.
