A semi‑classical Floquet‑NEGF approach to model photon‑assisted tunneling in quantum well devices
The non-equilibrium Green’s function formalism is often employed to model photon-assisted tunneling processes in opto-electronic quantum well devices. For this purpose, self-consistent schemes based on a quantum electrodynamical description of light–matter interactions have been proposed before. However, these schemes are
Analytic Differential Admittance Operator for Tangential Dipole Illumination of a Dielectric Sphere
In this paper, the exact differential surface admittance (DSA) operator for scattering analysis of a homogeneous dielectric sphere is constructed. By utilizing two sets of orthogonal vector spherical harmonics as the basis functions for a Galerkin Method of Moments, the
Exact Spectral Analysis of Traditional and Single-Source Integral Equations for a Penetrable Sphere
Behaviour of the numerical discretization schemes of the integral equations (IEs) such as the Method of Moments, the Locally Corrected Nystrom method and others largely depends on the spectral properties of the continuous integro-differential operators forming such equations. This includes
Analytic Differential Admittance Operator Solution of a Dielectric Sphere under Radial Dipole Illumination
In this contribution, the exact solution of the electric field integral equation (EFIE) combined with the differential surface admittance (DSA) operator is presented for scattering at a homogeneous dielectric sphere. By employing a Galerkin Method of Moments with two complete
Modeling of Tunable Electronic Waveguide Devices in Graphene using Conservative Higher-Order Time Stepping
An accurate technique leveraging conservative higher-order time stepping is proposed to analyze electrostatically induced waveguides in graphene. These highly tunable one-dimensional (1D) electronic channels are a promising interconnect alternative for graphene nanoribbons (GNRs) and carbon nanotubes (CNTs) to be used
Valley filtering in 8-Pmmn borophene based on an electrostatic waveguide constriction
Materials with tilted Dirac cones, such as 8-Pmmn borophene, are being explored for valleytronic applications as the tilting direction is different for nonequivalent valleys. In this paper, a valley-filtering device based on electrostatic waveguides is proposed. First, these waveguides are
