This paper proposes a new method for broadband terahertz detection using the nonlinear Hall effect in non-centrosymmetric quantum materials. The method utilizes the quadratic relationship between transverse current and input voltage to rectify terahertz radiation without any diode, offering potential advantages like zero threshold voltage, fast response speed, and high cutoff frequency.

This paper proposes a novel method for terahertz detection using the nonlinear Hall effect in quantum materials. The theoretical framework is well-developed, and the identified advantages, such as zero threshold voltage and fast response speed, are significant. However, the lack of extensive experimental validation and the dependence on specific material properties slightly lower the rating.
