Electric-field control of pure spin photocurrent in germanene
Yaqing Yang, Zhen Zhang, Liwen Zhang +4
The electrical control of pure spin current remains a central challenge in spintronics, particularly in time-reversal symmetric systems composed of nonmagnetic elements, where spin…
Disorder-driven exceptional points and concurrent topological phase transitions in non-Hermitian systems
Xiaoyu Cheng, Tiantao Qu, Yaqing Yang +2
Exceptional points (EPs) are spectral degeneracies unique to non-Hermitian systems which underpin phenomena from enhanced sensing to unconventional topology. While disorder is usua…
Electric field controlled valley-polarized photocurrent switch based on the circular bulk photovoltaic effect
Yaqing Yang, Xiaoyu Cheng, Liantuan Xiao +4
Efficient electric manipulation of valley degrees of freedom is critical and challenging for the advancement of valley-based information science and technology. We put forth an ele…
Photogalvanic effect induced charge and spin photocurrent in group-V monolayer systems
Li-Wen Zhang, Ya-Qing Yang, Jun Chen +1
Photogalvanic effect (PGE) occurs in materials with non-centrosymmetric structures when irradiated by linearly or circularly polarized light. Here, using non-equilibrium Green's fu…
