Investigation of electrical activity at the AlN/Si interface using scanning capacitance microscopy and scanning spreading resistance microscopy

Micka Bah, Damien Valente, Marie Lesecq, N. Defrance, Maxime Garcia Barros, Jean-Claude de Jaeger, Eric Frayssinet, Remi Comyn, Thi Huong Ngo, Daniel Alquier, Yvon Cordier

This work aims to understand the origin of propagation losses in GaN-on-Si devices at microwave frequencies thanks to original AFM's electrical modes such as scanning capacitance microscopy (SCM) and scanning spreading resistance microscopy (SSRM). AlN films on Si substrate were grown using…

Fluorine-based plasma treatment for AlGaN/GaN e-mode HEMTs and low on-voltage diodes

Quentin Fornasiero, N. Defrance, Marie Lesecq, Eric Frayssinet, Yvon Cordier, Florian Chevalier, Nadir Idir, Jean-Claude de Jaeger

The onset and pinch-off voltages shift of lateral GaN field-effect rectifier diodes (L-FER) and normally-off HEMTs are studied. It is shown that a short duration of low power SF6 plasma followed by a low temperature annealing permits to get an effective and stabilized fluorine ion implantation in…

GaN schottky diode on silicon substrate for high power THz multiplier

Giuseppe Di Gioia, M Samnouni, H Bouillaud, P Mondal, J Treuttel, Yvon Cordier, Malek Zegaoui, Guillaume Ducournau, Yannick Roelens, Mohammed Zaknoune

GaN-based planar Schottky barrier diodes with potential applications in THz frequency multipliers were fabricated on silicon substrate and characterized. GaN is a promising candidate to overcome all the physical limitations of GaAs which have been reached in the frame of high frequency power…

Subthreshold neuromorphic devices for spiking neural networks applied to embedded A.I

Christophe Loyez, Kevin Carpentier, Ilias Sourikopoulos, Francois Danneville

Energy autonomy is one of the major challenges of embedded Artificial Intelligence. Among the candidate technologies likely to take up such a challenge, spiking neural networks are the most promising because of both their spatio-temporal and sparse representation of the information. In this context…

Technological Parameters and Edge Fringing Capacitance in GaN Schottky Barrier Diodes: Monte Carlo Simulations

B. Orfao, B.G. Vasallo, D. Moro-Melgar, Mohammed Zaknoune, Giuseppe Di Gioia, M. Samnouni, S. Perez, T. Gonzalez, J. Mateos

Schottky barrier diodes (SBDs) with realistic geometries have been studied by means of a 2-D ensemble Monte Carlo simulator. The non-linearity of the Capacitance-Voltage (C-V) characteristic is the most important parameter for optimizing SBDs as frequency multipliers. In this paper, by changing the…
