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…
Electrical Control of Large Rashba Effect in Oxide Heterostructures
Yan Song, Dong Zhang, Ben Xu +2
Large Rashba effect efficiently tuned by an external electric field is highly desired for spintronic devices. Using first-principles calculations, we demonstrate that large Rashba…
