Room-temperature nonlinear Hall effect and wireless radiofrequency rectification in Weyl semimetal TaIrTe4

The nonlinear Hall effect (NLHE), which can produce a transverse voltage without any magnetic field, is potential alternative for rectification or frequency doubling. However, the low temperature detection of NLHE limits its applications. Here, we report room-temperature in type-II Weyl semimetal TaIrTe4, hosts robust due to substantial broken inversion symmetry and large band overlapping at Fermi level. We also observe temperature-induced sign TaIrTe4. Our theoretical calculations suggest that observed result shift chemical indicating direct correlation with electronic structure surface. Finally, TaIrTe4 exploited demonstrate wireless RF zero external bias field. This work opens door realizing room applications based on semimetals.
