Combined STM and four-probe resistivity measurements on single semiconductor nanowires

Maxime Berthe, Corentin Durand, Tao Xu, Jean-Philippe Nys, Philippe Caroff, B. Grandidier

Transport measurements on free-standing nanostructures with clean and reconstructed facets require an instrumentation based on electrical probes that scan materials at the atomic scale with fine tuning in the establishment of the electrical contact. We describe a multiple probe tunneling microscope…

Demonstration of low leakage current and high polarization in ultrathin AlN/GaN high electron mobility transistors grown on silicon substrate

F Medjdoub, Malek Zegaoui, N. Rolland, Paul-Alain Rolland

High quality AlN/GaN heterostructures grown on silicon substrate are demonstrated. It is found that high carrier concentration can be achieved whereas circular diodes showed a low leakage current up to 200 V reverse bias. 200 nm gate length AlN/GaN transistors exhibited a drain current density of 1…

Size-dependent catalytic and melting properties of platinum-palladium nanoparticles

G. Guisbiers, G. Abudukelimu, D. Hourlier

While nanocatalysis is a very active field, there have been very few studies in the size/shape-dependent catalytic properties of transition metals from a thermodynamical approach. Transition metal nanoparticles are very attractive due their high surface to volume ratio and their high surface energy…

A controllable bandwidth filter using varactor-loaded metamaterial-inspired transmission lines

Alejandro Borja, Jorge Carbonell, Jorge D. Martinez, Vicente Boria, Didier Lippens

This letter presents a tunable bandwidth bandpass filter based on varactor-loaded metamaterial coplanar waveguide (CPW) lines. The CPW lines are based on series gaps and split-ring resonators. The varactors are reverse-biased semiconductor diodes connected between both sides of each series gap.…

Negative refraction of elastic waves in 2D phononic crystals : contribution of resonant transmissions to the construction of the image of a point source

Anne-Christine Hladky, Charles Croënne, Bertrand Dubus, Jerome O. Vasseur, L. Haumesser, D. Manga, B. Morvan

Negative refraction properties of a two-dimensional phononic crystal (PC), made of a triangular lattice of steel rods embedded in epoxy are investigated both experimentally and numerically. First, experiments have been carried out on a prism shaped PC immersed in water. Then, for focusing purposes…
