AlN-based HEMTs grown on silicon substrate by NH3-MBE

Stephanie Rennesson, Fabrice Semond, M. Nemoz, Jeans Massies, Stéphane Chenot, Ludovic Largeau, Ezgi Dogmus, Malek Zegaoui, F Medjdoub

In this paper, AlN-based HEMTs on silicon are demonstrated using NH3-MBE. The spirit is to get the highest 2DEG density theoretically achievable in nitrides while keeping thin barrier thickness, which is mandatory to achieve high frequency performances. To do that, the strategy consists in growing…

Advances in silicon surface texturization by metal assisted chemical etching for photovoltaic applications

Sylvain Le Gall, Raphaël Lachaume, Encarnacion Torralba, Mathieu Halbwax, Vincent Magnin, Taha El Assimi, Marin El Fouchier, Joseph Harari, Jean-Pierre Vilcot, Christine Cachet-Vivier, Stéphane Bastide

— New Si processes based on Metal Assisted Chemical Etching (MACE) are explored for solar cells texturization. Pt and Au are considered as catalysts for MACE of p and n-type Si substrates. 2D band bending modeling at the nanoscale shows that Pt nanoparticles (NPs) make ohmic contacts and induce…

Memristor Device Characterization by Scanning Microwave Microscopy

Gilbert Sassine, N. Najjari, Charlene Brillard, N. Defrance, Olaf C Haenssler, Didier Theron, F. Alibart, Kamel Haddadi

We report memristive device characterization using near-field scanning microwave microscopy. Atomic force microscopy, magnitude and phase-shift images of the complex reflection coefficient of TiO2 devices can be acquired simultaneously in the range 1-20 GHz. In particular, measurement of the…

An original approach to elastic constants determination using a self-developed EMAT system

Frédéric Jenot, Frédéric Rivart, Liévin Camus

Electromagnetic Acoustic Transducers (EMATs) allow non-contact ultrasonic measurements in order to characterize structures for a wide range of applications. Considering non-ferromagnetic metal materials, excitation of elastic waves is due to Lorentz forces that result from an applied magnetic field…
