ABSTRACT
The low-temperature superconductivity and topological properties of two-dimensional PdTe2 have shown great potential in the fields of optics and electronics, and its electrical and thermal transport properties under a strong magnetic field are very important for basic research and practical applications. In this study, the electrical resistivity and thermal conductivity of high crystalline PdTe2 nanoribbons were comprehensively measured by applying the direct current heating method, eliminating the thermal and electrical contact resistances at different magnetic field intensities and temperatures. It is found that the PdTe2 nanoribbons exhibited a low electrical resistivity of â¼27 µΩ cm and a high thermal conductivity of â¼130 W m-1 K-1 at room temperature. Moreover, the magnetoresistance of PdTe2 nanoribbons increased with the decrease in temperature and reached 114% at 20 K and 14 T. The thermal conductivity change rate caused by the 14 T magnetic field increased at low temperatures, reaching -11.3% at 20 K.
