摘要： Two-dimensional tellurium (2D-Te) exhibits strong spin-orbit coupling and a chiral structure. Studying its magnetotransport properties is crucial for the development of spintronic technologies and the exploration of novel device applications. The magnetotransport properties of 2D-Te under varying temperatures and high pressures warrant further study. In this paper, the magnetotransport behavior of 2D-Te under low-temperature and high-pressure conditions is investigated. At room temperature, the magnetoresistance (${\rm MR}$) increases with increasing magnetic field, exhibiting positive ${\rm MR}$ behavior below 4.3 GPa. During decompression, ${\rm MR}$ is almost constant with decreasing pressure. ${\rm MR}$ is more sensitive to pressure at lower temperatures.
