Abstract

Nonlinear electron transport induced by polarized terahertz radiation is studied in two-dimensional tellurene at room temperature. A direct current, quadratic in the radiation's electric field, is observed. Contributions sensitive to radiation helicity and polarization orientation as well as polarization independent current are found. We show that these contributions can be modified by the magnitude of the external gate potential. We demonstrate that this terahertz-driven electric current arises from the Berry curvature dipole and the side-jump microscopic mechanisms.

摘要

在室温下的二维碲烯中研究了极化太赫兹辐射诱导的非线性电子输运。观测到了与辐射电场呈二次方关系的直流电流。发现了对辐射螺旋度和极化方向敏感的贡献以及与极化无关的电流。我们表明，这些贡献可以通过外部栅极电势的大小来改变。我们证明，这种太赫兹驱动的电流源于贝里曲率偶极子和侧跳微观机制。
