@article{Kumar2021RoomtemperatureNH, title={Room-temperature nonlinear Hall effect and wireless radiofrequency rectification in Weyl semimetal TaIrTe4}, author={Dushyant Kumar and Chuanghan Hsu and Raghav Sharma and Tay-Rong Chang and Peng Yu and Junyong Wang and Goki Eda and Gengchiau Liang and Hyunsoo Yang}, journal={Nature Nanotechnology}, year={2021}, volume={16}, pages={421 - 425} }

The nonlinear Hall effect (NLHE), the phenomenon in which a transverse voltage can be produced without a magnetic field, provides a potential alternative for rectification or frequency doubling1,2. However, the low-temperature detection of the NLHE limits its applications3,4. Here, we report the room-temperature NLHE in a type-II Weyl semimetal TaIrTe4, which hosts a robust NLHE due to broken inversion symmetry and large band overlapping at the Fermi level. We also observe a temperature-induced…
