Three-dimensional Monte Carlo study of three-terminal junctions based on InGaAs/InAlAs heterostructures

T. Sadi, F. Dessenne, Jean-Luc Thobel

We apply a three-dimensional (3D) semiclassical ensemble Monte Carlo simulation method to study T-branch junctions based on InGaAs/InAlAs heterostructures and obtain an accurate insight into the physics behind the operation of such structures. Electron transport in these devices is investigated and…

Defect modes in one-dimensional anisotropic photonic crystal

Noama Ouchani, Driss Bria, Bahram Djafari-Rouhani, Abdlekarim Nougaoui

We theoretically analyze the defect states in a single-defect photonic crystal composed of anisotropic dielectric materials. This structure can trap light of a given frequency range and filter only a certain frequency light. It is shown that the defect modes appear as peaks in the transmission…

Electrons in quantum dots : one by one

S. Gustavsson, R. Leturcq, T. Ihn, K. Ensslin, A.C. Gossard

A quantum point contact placed close to a quantum dot can be used as a charge detector with time resolution to monitor the charge flow on the level of individual electrons. The current through the quantum point contact may take two possible values corresponding to the situation of an additional…
