Electron transport and scattering mechanisms in ferromagnetic monolayer FeGeTe
arXiv:2302.10974 · doi:10.1038/s41699-023-00413-0
Abstract
We study intrinsic charge-carrier scattering mechanisms and determine their contribution to the transport properties of the two-dimensional ferromagnet FeGeTe. We use state-of-the-art first-principles calculations combined with the model approaches to elucidate the role of the electron-phonon and electron-magnon interactions in the electronic transport. Our findings show that the charge carrier scattering in FeGeTe is dominated by the electron-phonon interaction, while the role of magnetic excitations is marginal. At the same time, the magnetic ordering is shown to effect essentially on the electron-phonon coupling and its temperature dependence. This leads to a sublinear temperature dependence of the electrical resistivity near the Curie temperature, which is in line with experimental observations. The room temperature resistivity is estimated to be 35 cm which may be considered as an intrinsic limit for monolayer FeGeTe.
