“…Compared with nanoribbons 12,24,25 , GALs can carry a much higher electrical current for applications in electronic devices. Beyond field effect transistors, GALs have been suggested for their wide applications in gas sensing 26 , thermoelectric power generation and cooling 27,28 , optoelectronic devices 29 , magnetics 30,31 , spintronics 32,33 and waveguides 34 . Along this line, numerous simulations and measurements have been carried out to understand the structuredependent electrical properties of GALs.…”

Charge carrier scattering is critical to the electrical properties of two-dimensional materials such as graphene, transition metal dichalcogenide monolayers, black phosphorene, and tellurene. Beyond pristine two-dimensional materials, further tailored properties can be achieved by nanoporous patterns such as nano-or atomic-scale pores (antidots) across the material. As one example, structure-dependent electrical/optical properties for graphene antidot lattices (GALs) have been studied in recent years. However, detailed charge carrier scattering mechanism is still not fully understood, which hinders the future improvement and potential applications of such metamaterials. In this paper, the energy sensitivity of charge-carrier scattering and thus the dominant scattering mechanisms are revealed for GALs by analyzing the maximum Seebeck coefficient with a tuned gate voltage and thus shifted Fermi levels. It shows that the scattering from pore-edge-trapped charges is dominant, especially at elevated temperatures. For thermoelectric interests, the gate-voltage-dependent power factor of different GAL samples are measured as high as 554 μW/cm·K at 400 K for a GAL with the square

“…Surface plasmon polaritons (SPPs) are electromagnetic waves that propagate along the surface of precious metals, which is generated by the interaction of input light and free electrons of metal, and decay exponentially away from the interface [1,2]. Dispersion relations, excitation modes and coupling effects of SPPs are determined by the metal surface structure, which can be used to control the light propagation [3][4][5].…”

A plasmon structure based on a metal-insulator-metal (MIM) waveguide composed of three stubs (TSs) is proposed, and its transmission characteristics are studied numerically by the finite element method (FEM). The simulation results show that multiple plasmon-induced transparencies (PITs) with high transmission can be produced in the structure and can be tuned effectively. By adjusting the structure parameters, more high-order PITs with narrower window are generated. Furthermore, the proposed MIM waveguide is sensitive to the environment and the maximum values of refractive index sensitivity and figure of merit (FOM) are 1340 nm R−1IU−1 and 251/RIU, respectively. Multiple, adjustable and narrow PITs with high FOM can be induced in the proposed structure, which can be used in the fields of multi-channel filters, optical switches, storages, sensors, and so on.

“…The realization of the EIT effect requires stable gas lasers and rigorous environments, which hampers its practical applications. Recently, kinds of configurations have been proposed to mimic EIT-like transmission without the demand of rigorous experimental conditions, including coupled micro-resonators [8–12], split-ring, and metamaterials [13–16] composed of dielectric and metal materials. Among them, metamaterial-based EIT with periodic unit patterns requires an excited signal light incident in the direction non-parallel to the chip surface.…”

Plasmon-induced transparency is an efficient way to mimic electromagnetically induced transparency, which can eliminate the opaque effect of medium to the propagating electromagnetic wave. We proposed an aperture-side-coupled asymmetric bowtie structure to realize on-chip plasmon-induced transparency in optical communications band. The plasmon-induced transparency results from the strong coupling between the detuned bowtie triangular resonators. Either of the resonator works as a Fabry-Perot cavity with compact dimensions. The transparent peak wavelength can be easily controlled due to its strong linear relation with the resonator height. The ratio of absorption valley to the transparent peak can be more than 10 dB. Moreover, with excellent linearity of shifting wavelength to sensing material index, the device has great sensing performance and immunity to the structure deviations.
