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-…

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…

On-line tools for microscopic and macroscopic monitoring of microwave processing

S. Vaucher, P. Unifantowicz, C. Ricard, Luc Dubois, M. Kuball, J.-M. Catala-Civera, Dominique Bernard, M. Stampanoni, R. Nicula

Direct monitoring of temperature, chemistry and microstructure is required to understand microwave heating in more detail, in order to fully exploit the unique features this non-equilibrium processing method can offer. In this paper, we show first that microwave radiometry can be used to follow…
