论文摘要
我们提出了一种内在的非线性平面霍尔效应，该效应是带状几何起源的，独立于散射，并且具有二阶电场和一阶磁场的尺度。我们表明，与其他非线性转运效应相比，这种效应受到的对称性较小，并且在一大类非磁性极性和手性晶体中得到了支持。它的特征角依赖性提供了一种控制非线性输出的有效方法。结合第一原理计算，我们在Janus单层Mosse中评估了这种效果，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运输效果，该效果为材料表征提供了新的工具，并为非线性设备应用提供了新的机制。
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 to 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.
