| Abstract | We have studied electric and thermal transport properties in two-dimensional van der Waals ferromagnetic Fe3GeTe2. The low-temperature longitudinal resistivity measured in the ab plane is contributed by the impurity scattering, the quantum correction, and the electron-electron interaction. Meanwhile, the low-temperature specific heat consists of linear and cubic temperature terms, corresponding to contributions of electrons and phonons, respectively. Therefore, the heavy-fermion state in Fe3GeTe2 can be described by Landau's Fermi liquid theory. The Kadowaki-Woods ratio in Fe3GeTe2 is five times larger and smaller than the values of transition metals and heavy-fermion compounds, respectively. Moreover, the thermal conductivity measured along the c axis increases monotonically with temperature, exhibiting a phonon glass electron crystal behavior, due to the dominant role of boundary scattering of phonons. The T1.35 dependence of the lattice thermal conductivity observed at low temperatures arises from a combined effect of the highly anisotropic dispersion and strong impurity scattering of phonons. © 2023 American Physical Society. |
