Tunable nonlinear Hall effect observed in tellurium at room temperature.

Schematic structure of Te flakes and the performance of NLHE in Te devices. Credit: Prof. Zeng’s team The team discovered a remarkable nonlinear Hall effect and radio rectification effect at room temperature in the elemental semiconductor tellurium (Te). The study is published in Nature Communications. The Nonlinear Hall Effect (NLHE) is a second-order response to an applied alternating current (AC)…
