The second order nonlinear Hall effect leads to a direct voltage generated from the rectification effect. While this rectification property is appeal for use in devices, most materials exhibiting a second order nonlinear hall effect are constrained to low temperatures. Here, Lu et al demonstrate a second order nonlinear transport behaviour that persists above room temperature in BiTeBr, and construct a prototype rectifier based on this effect.
