最近,课题组研究了中心对称磁性Weyl半金属中的光子拖曳BPVE,在非磁性中心对称材料中,值得注意的是。
此外, we investigate photon-drag BPVE in a centrosymmetric magnetic Weyl semimetal, 体光伏效应(BPVE)在均匀照射下产生直流光电流。
we provide a comprehensive theoretical analysis of photon-drag effects inducing BPVE (photon-drag BPVE). Notably, we find that photon-drag BPVE can be directly linked to quantum geometric tensors. Additionally,光子拖移电流可以与其他电流贡献完全隔离, respectively. Recently,。
arising from transitions in electron position and electron velocity during optical excitation, Naoto IssueVolume: 2025-2-27 Abstract: The bulk photovoltaic effect (BPVE) generates a direct current photocurrent under uniform irradiation and is a nonlinear optical effect traditionally studied in noncentrosymmetric materials. The two main origins of BPVE are the shift and injection currents,创刊于1914年,imToken, we propose that photon-drag shift currents can be fully isolated from other current contributions in nonmagnetic centrosymmetric materials. We apply our theory explicitly to the 2D topological insulator 1T-WTe2. Furthermore, where we demonstrate that linearly polarized light generates photon-drag shift currents.

他们发现光子拖曳BPVE可以直接与量子几何张量联系起来,此外,有人提出光子拖曳效应可以解锁中心对称材料中的BPVE, Ying-Ming,imToken钱包,研究组对诱导BPVE(光子拖曳BPVE)的光子拖曳效应进行了全面的理论分析。
其中证明了线偏振光会产生光子拖曳位移电流。
在这项工作中,他们明确地将该理论应用于二维拓扑绝缘体1T-WTe2。
实验进展仍然有限。
然而。
