Dual-Mode On-to-Off Modulation of Plasmon-Induced Transparency and Coupling Effect in Patterned Graphene-Based Terahertz Metasurface.
Zhimin Liu,Zhimin Liu,Enduo Gao,Zhenbin Zhang,Hongjian Li,Hui Xu,Xiao Zhang,Xin Luo,Fengqi Zhou +8 more
TL;DR: The proposed structure provides a new basis for the dual-mode on-to-off multi-function modulators in patterned graphene-based terahertz metasurface composed of graphene ribbons and graphene strips.
Journal ArticleDOI
Theoretical predictions on the electronic structure and charge carrier mobility in 2D Phosphorus sheets
TL;DR: It is shown that α-P, β-P and γ-P are indirect gap semiconductors, while δ-P is a direct one, and all four sheets have ultrahigh carrier mobility and show anisotropy in-plane.
Journal ArticleDOI
Absorption and slow-light analysis based on tunable plasmon-induced transparency in patterned graphene metamaterial.
TL;DR: It is found that the absorption efficiency of the designed structure can reach up to 50%, meaning the structure is competent to prominent terahertz absorber, and the slow-light performance of this structure is discussed via analyzing the group refractive index and phase shift.
Journal ArticleDOI
Dynamically tunable dual plasmon-induced transparency and absorption based on a single-layer patterned graphene metamaterial
Enduo Gao,Zhimin Liu,Hongjian Li,Hui Xu,Zhenbin Zhang,Xin Luo,Cuixiu Xiong,Chao Liu,Baihui Zhang,Fengqi Zhou +9 more
TL;DR: Electric field distribution and coupled mode theory are used to demonstrate the physical mechanism of dual PIT and PIA, and the theoretical result of CMT is highly consistent with the finite-difference time-domain (FDTD) method simulation result.
Journal ArticleDOI
Chemical Functionalization of Graphene Nanoribbons by Carboxyl Groups on Stone-Wales Defects
TL;DR: In this article, the density functional theory was used to demonstrate the chemical functionalization of semiconducting graphene nanoribbons (GNRs) with Stone-Wales (SW) defects by carboxyl (COOH) groups.
