Atomic configuration controlled photocurrent in van der Waals homostructures
Ying Xiong, Li-kun Shi, Justin C. W. Song
Conventional photocurrents at a p-n junction depend on macroscopic built-in fields and are typically insensitive to the microscopic details of a crystal's atomic configuration. Her…

Geometric photon-drag effect and nonlinear shift current in centrosymmetric crystals
Li-kun Shi, Dong Zhang, Kai Chang +1
The nonlinear shift current, also known as the bulk photovoltaic current generated by linearly polarized light, has long been known to be absent in crystals with inversion symmetry…

Cooperative orbital moments and edge magnetoresistance in monolayer WTe
Arpit Arora, Li-kun Shi, Justin C. W. Song
We argue that edge electrons in monolayer WTe can possess a "cooperative" orbital moment (COM) that critically impacts its edge magnetoresistance behavior. Arising from the coo…
