Autor: O. Vanbésien, N. Ben Abdallah, Eric Polizzi, D. Lippens
Publikováno v: Scopus-Elsevier
Nonlinear conduction properties of multiport quantum waveguide-based devices are theoretically investigated. A two dimensional finite element solver for the time independent Schrodinger equation combined with Poisson equation has been developed. It h

Autor: Daniel Pardo, Ferran Martin, O Vanbésien, Tomas Gonzalez, Joan Garcia-Garcia, Xavier Oriols, Jordi Suñé, Javier Mateos
Publikováno v: Semiconductor Science and Technology. 14:532-542
Following the path of a previous letter, a generalization of the classical Monte Carlo (MC) device simulation technique is proposed with the final goal of simultaneously dealing with phase-coherence effects and scattering interactions in quantum-base

An analysis of wave patterns in multiport quantum waveguide structures
Autor: Didier Lippens, O Vanbésien, Ludovic Burgnies
Publikováno v: Journal of Physics D: Applied Physics. 32:706-712
Wave patterns in two- and four-port quantum waveguide structures are reported in order to analyse the operating modes of T-stub, single-branch and double-branch quantum couplers. The ballistic transport study is carried out using mode-matching techni

Dual-branch electron waveguide couplers
Autor: O. Vanbésien, Didier Lippens
Publikováno v: Materials Science and Engineering: B. 35:90-96
A quantum directional coupler which consists of two electron waveguides interconnected by a dual branch line scheme is analysed. With respect to a structure with a single interaction window, the crucial advantage is that the phase in the output leads

Publikováno v: Superlattices and Microstructures. 17:197-200
A novel planar electron waveguide coupler is proposed as an electronic switch. The structure consists of two quantum wires interconnected by a dual branch coupling scheme which is assumed to be controlled by an electrostatic potential. Switching is p

Publikováno v: Microwave and Optical Technology Letters. 33:134-136
In this work, a detailed analysis of two different approaches to the simulation of nonlinear transmission lines (NLTLs) is presented. Distributed and lumped-element models have been compared, and it has been shown that the latter (and simpler) approa

Theoretical analysis of a branch line quantum directional coupler
Autor: O. Vanbésien, D. Lippens
Publikováno v: Applied Physics Letters. 65:2439-2441
We propose a new quantum directional coupler which consists of two parallel electron waveguides coupled by branch lines. The component is based on a high mobility modulation‐doped heterostructure, where the channel is constricted by a double H gate
