Local Optical Conductivity of Bilayer Graphene with Kink Potential
Zhen-Bing Dai, Zhiqiang Li, Yan He
We study the optical response of bilayer graphene with a kink potential composed of a domain wall separating two AB regions with opposite interlayer bias. The band structure and th…
Effects of heterostrain and lattice relaxation on optical conductivity of twisted bilayer graphene
Zhen-Bing Dai, Yan He, Zhiqiang Li
We present a theoretical study of the effects of heterostrain and lattice relaxation on the optical conductivity of twisted bilayer graphene near the magic angle, based on the band…
Multiple Hot-Carrier Collection in Photo-Excited Graphene Moire Superlattices
Sanfeng Wu, Lei Wang, You Lai +10
In conventional light harvesting devices, the absorption of a single photon only excites one electron, which sets the standard limit of power-conversion efficiency, such as the Sho…
Imaging Stacking Order in Few-Layer Graphene
Chun Hung Lui, Zhiqiang Li, Zheyuan Chen +3
Few-layer graphene (FLG) has been predicted to exist in various crystallographic stacking sequences, which can strongly influence the electronic properties of FLG. We demonstrate a…
