We present a transmission line model for TM plasmon propagation along a graphene strip, and derive closed-form expressions for the kinetic and Faraday inductance, resistance, and electrostatic capacitance of the equivalent circuit as a function of graphene ...
The plane wave scattering and absorption by finite and infinite gratings of free-space standing infinitely long graphene strips are studied in the THz range. A novel numerical approach, based on graphene surface impedance, hyper-singular integral equations ...
Graphene, a honeycomb lattice of a single atom thick plane of carbon atoms has captivated the attention of physicists, materials scientists, and engineers because of its extraordinary physical properties. These include exceedingly high charge carrier mobil ...
Graphene, a single layer of carbon atoms, exhibits excellent charge transport properties. However, due to the absence of a band gap in this two-dimensional carbon nanostructure, graphene-based field effect transistors cannot be turned off. One strategy to ...
We present recent results related to the modelling, design, and application of graphene surfaces. Mono and multilayer graphene surfaces are patterned in a periodic or quasi-periodic manner to tailor their electromagnetic response in terms of magnitude, pha ...
With transistors set to reach their smallest possible size in the next decade, the silicon chip is likely to change dramatically, or be replaced entirely. The transistor industry's path which has been largely shaped by Gordon Moore's famous prediction that ...
The concept and analysis of a terahertz (THz) frequency-reconfigurable antenna using graphene are presented. The antenna exploits dipole-like plasmonic resonances that can be frequency-tuned on large range via the electric field effect in a graphene stack. ...
The great achievement of nanotechnology is the controlled synthesis of a large variety of nanometer-size materials like needle-formed nanotubes, nanowires and two-dimensional graphene flakes. Due to their unique physico-chemical properties, these nanostruc ...
This is the second part of two articles reporting investigation on a thermal-detector-type far-infrared sensor operating in the 8–14 µm wavelength region using Low-Pressure Chemical Vapor Deposition (LPCVD) deposited low-stress Si-rich nitride (SiN) membra ...
In this thesis we study the electronic structure of different two-dimensional (2D) electron systems with angular resolved photoemission spectroscopy (ARPES). This technique is based on the photoelectric effect and directly probes the electronic structure o ...
