Résumé :

An atomic-scale finite element method was applied to analyze the sensitivities of α-, β-, γ-, and 6,6,12-graphyne-based resonators in mass detection under different boundary conditions. These sensitivities are then compared with that of a graphene-based resonator obtained in a previous study. According to the analysis results, among the graphyne-based resonators, the α type shows the highest sensitivity, while the γ type shows the lowest. In addition, the sensitivity decreases as the resonator size increases. We also find that the location of the attached mass has a significant effect on the s

Résumé :

Abstract The low-quality factor is a key bottleneck for the engineering and commercial application of graphene nanoelectromechanical resonators at room temperature. The hypothesis in dissipation dominated by the ohmic loss is difficult to cover this phenomenon. Mechanical loss may still be on the list of the main causes for the quality factor stress-modulation characteristics of graphene resonators. The dissipation dilution theory reveals the intrinsic energy and dissipation mechanism of the traditional high-stress silicon-based resonator, which may also be applied to two-dimensional (2D) mate

Résumé :

We have studied the finite-size effect on the dynamic behavior of graphene resonators and their applications in atomic mass detection using a continuum elastic model such as modified plate theory. In particular, we developed a model based on von Karman plate theory with including the edge stress, which arises from the imbalance between the coordination numbers of bulk atoms and edge atoms of graphene. It is shown that as the size of a graphene resonator decreases, the edge stress depending on the edge structure of a graphene resonator plays a critical role on both its dynamic and sensing perfo

Résumé :

We demonstrated a multi-band plasmonic metamaterial absorber (MA), based on the near-field coupled resonators. In addition to the individual resonances of resonators in the proposed structure, which were split-ring resonator (SRR) and cross-shape structures, another resonance was also excited owing to the coupling of resonators, revealing a triple-band absorption. Furthermore, to control the absorption behavior, on the top of the SRRs, the identical SRRs made of graphene ink were pasted. By increasing the resistance of graphene ink, the coupling strength was weakened, changing the triple-band

Graphene resonant sensors have shown strong competitiveness with respect to sensitivity and size. To advance the applications of graphene resonant sensors, the damage behaviors of graphene harmonic oscillators after thermal annealing and laser irradiation were investigated by morphology analysis and frequency domain vibration characteristics.

Thanks to the tunable permittivity of graphene by bias voltages, the resonant wavelength of side-coupled resonators can be changed.

Résumé :

In this paper, a novel method to realize a dynamically tunable analogue of EIT for the resonance strength rather than the resonance frequency is proposed in the terahertz spectrum. The introduced method is composed of a metal EIT-like structure, in which a distinct EIT phenomenon resulting from the near field coupling between bright and dark mode resonators can be obtained, as well as an integrated monolayer graphene ribbon under the dark mode resonator that can continuously adjust the resonance strength of transparency peak by changing the Fermi level of the graphene. Comparing structures tha

Résumé :

Nonlinear TE-polarized surface plasmons localized at the interface between graphene and metamaterials are investigated analytically. The normalized momentum of graphene surface plasmons at the interface between graphene and metamaterials composed of arrays of wires and split-ring resonators (SRR) embedded into a nonlinear dielectric exhibits bistable behavior with the magnetic field intensity. The effect is explained by the hysteresis-type dependence of the nonlinear permeability of metamaterials on the field intensity.

Résumé :

The tunable terahertz (THz) Fano-resonant filter based on hybrid metal-graphene metamaterial was proposed. The optical parameters of metasurface with unit cell in the form of a cross-shaped graphene sheet in the center of a square gold ring were simulated by the finite element method using a surface conductivity model of a graphene monolayer. The narrowband modulation of the transmission by varying the Fermi level of the graphene and the position of graphene cross inside the metal ring was demonstrated. Simulation results were well explained theoretically using a three-coupled oscillator model

Résumé :

Reflective metasurfaces for arbitrary wave-front control require unit cells to achieve both [Formula: see text] phase rotation and unity amplitude in reflection waves, and such requirements are a fundamental challenge for ultra-thin metasurfaces without the use of a metallic plate. We analytically show that in two coupled resonators, tuning the resonance frequency with the external decay rate for one of the resonators enables near [Formula: see text] phase rotation and unity amplitude in the reflection wave, where no reflector is required. We implement the mechanism on a reflective graphene me
