Terahertz conductivity of twisted bilayer graphene
Xingquan Zou, Jingzhi Shang, Jianing Leaw +11
Using terahertz time-domain spectroscopy, the real part of optical conductivity [] of twisted bilayer graphene was obtained at different temperatures (10 -- 300 K) in the…
Direct Observation of Inner and Outer G' Band Double-resonance Raman Scattering in Free Standing Graphene
Zhiqiang Luo, Chunxiao Cong, Jun Zhang +2
In contrary to the widely reported single and symmetric peak feature of G' (or 2D) band in Raman spectrum of graphene, we herein report the observation of splitting in G' band in f…
Nonlinear graphene metamaterial
Andrey E. Nikolaenko, Nikitas Papasimakis, Evangelos Atmatzakis +6
We demonstrate that the broadband nonlinear optical response of graphene can be resonantly enhanced by more than an order of magnitude through hybridization with a plasmonic metama…
Large Scale Synthesis of Bi-layer Graphene in Strongly Coupled Stacking Order
Zhiqiang Luo, Ting Yu, Jingzhi Shang +6
Large scale synthesis of single layer graphene (SLG) by chemical vapor deposition (CVD) has received a lot of attention recently. However, CVD synthesis of AB stacked bi-layer grap…
Ultrafast carrier dynamics in pristine and FeCl3-intercalated bilayer graphene
Xingquan Zou, Da Zhan, Xiaofeng Fan +9
Ultrafast carrier dynamics of pristine bilayer graphene (BLG) and bilayer graphene intercalated with FeCl3 (FeCl3-G), were studied using time-resolved transient differential reflec…
Electronic Structure and Structural Evolutions of Hydrogenated Graphene Probed by Raman Spectroscopy
Zhiqiang Luo, Ting Yu, Zhenhua Ni +6
The electronic structure and structural evolution of hydrogenated graphene are investigated by Raman spectroscopy with multiple excitations. The excitation energy dependent saturat…
