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…

Thermal characterization of MBE-grown GaN/AlGaN/GaN device on single crystalline diamond

J. Kuzmik, S. Bychikhin, D. Pogany, E. Pichonat, O. Lancry, Christophe Gaquière, G. Tsiakatouras, G. Deligeorgis, A. Georgakilas

Self-heating effects in a molecular beam epitaxy-grown GaN/AlGaN/GaN structure on a single crystalline diamond is investigated. A transient interferometric method, in combination with a three dimensional model, is used to describe a pulsed operation of a transistor-like heater, and a micro-Raman…

Electrical characterization of (Ni/Au)/Al0.25Ga0.75N/GaN/SiC Schottky barrier diode

S. Saadaoui, M.M. Ben Salem, M. Gassoumi, H. Maaref, Christophe Gaquière

In this work we report on the characteristics of a (Ni/Au)/AlGaN/GaN/SiC Schottky barrier diode (SBD). A variety of electrical techniques, such as gate current-voltage (I-V), capacitance-voltage (C-V), and deep level transient spectroscopy (DLTS) measurements have been used to characterize the…

Dielectric dispersion of BaSrTiO3 thin film from centimeter to submillimeter wavelengths

Grégory Houzet, Karine Blary, Sylvie Lepilliet, Didier Lippens, Ludovic Burgnies, Gabriel Vélu, Jean-Claude Carru, Edwin Nguema Agnandji, Patrick Mounaix

The dielectric dispersion of ferroelectric BaxSr1-xTiO3 (BST) thin film in a paraelectric phase was characterized from centimeter to submillimeter wavelengths. To this aim, interdigitated capacitors were patterned on a micrometer scale onto a BST layer with a barium concentration of 0.5 and were…
