We propose an intrinsic nonlinear planar Hall effect, which is of band geometric origin, independent of scattering, and scales with the second order of electric field and first order of magnetic field. We show that this effect is less symmetry constrained compared with other nonlinear transport effects and is supported in a large class of nonmagnetic polar and chiral crystals. Its characteristic angular dependence provides an effective way to control the nonlinear output. Combined with first-principles calculations, we evaluate this effect in the Janus monolayer MoSSe and report experimentally measurable results. Our work reveals an intrinsic transport effect, which offers a new tool for material characterization and a new mechanism for nonlinear device application.

固有非线性平面霍尔效应

我们提出了一种本征非线性平面霍尔效应，它具有带几何原点，与散射无关，并且与电场的二阶和磁场的一阶成比例。我们表明，与其他非线性传输效应相比，这种效应的对称性约束较少，并且在一大类非磁性极性和手性晶体中得到支持。其特有的角度依赖性提供了一种控制非线性输出的有效方法。结合第一性原理计算，我们评估了 Janus 单层 MoSSe 中的这种效应，并报告了实验可测量的结果。我们的工作揭示了一种内在的传输效应，它为材料表征提供了一种新工具，并为非线性器件应用提供了一种新机制。
