Imaging electron wave functions inside open quantum rings

F. Martins, B. Hackens, Marco G. Pala, Thierry Ouisse, Hermann Sellier, X. Wallart, S. Bollaert, A. Cappy, Joël Chevrier, V. Bayot, Serge Huant

Combining Scanning Gate Microscopy (SGM) experiments and simulations, we demonstrate low temperature imaging of electron probability density $|\Psi|^{2}(x,y)$ in embedded mesoscopic quantum rings (QRs). The tip-induced conductance modulations share the same temperature dependence as the Aharonov-…

Physical study of the dissipated power area in high electron mobility transistors for thermal modelling

Brahim Benbakhti, Michel Rousseau, Jean-Claude de Jaeger

The hot area in power transistors due to the power dissipation is determined from a 2D-hydrodynamic model. The power is calculated everywhere in the device from the knowledge of the physical quantities (current density, electric field). The hot area is determined accurately to be coupled to a…

Development and analysis of low resistance ohmic contact to n-AlGaN/GaN HEMT

A. Soltani, A. Ben Moussa, S. Touati, Virginie Hoel, Jean-Claude de Jaeger, J. Laureyns, Y. Cordier, C. Marhic, M. A. Djouadi, C. Dua

High quality ohmic contacts were realized in order to obtain an AlGaN/GaN high electron mobility transistor (HEMT) on different substrates (Si, Al2O3, SiC). A metallization scheme based on Ti/Al/Ni/Au was used. The ohmic contacts were obtained using an optimized rapid thermal annealing (RTA) at…

All-optical tunability of InGaAsP/InP microdisk resonator by infrared light irradiation

Maxime Beaugeois, Bernard Pinchemel, Mohamed Bouazaoui, Marie Lesecq, Sophie Maricot, Jean-Pierre Vilcot

We report the optical characterization of an InP structure constituted by waveguides coupled to microcavity disk resonators. The lateral waveguide confinement is obtained by deep reactive ion etching through the guiding layer. We demonstrate the possibility of tuning optically the resonance…
