Power Handling of GaN Schottky Diodes on Semi-Insulating Ammonothermal GaN Substrate at 94 GHz

Mahmoud ABOU DAHER, Hugo Bouillaud, Pawel Prystawko, Michal Bockowski, Etienne Okada, Malek Zegaoui, Guillaume Ducournau, Yannick Roelens, Mohammed Zaknoune

In this paper, we report electrical results and handling power results of different Schottky diodes based on 620 nm of n- Gallium Nitride (GaN) fabricated on ammonothermal GaN substrate. The breakdown voltage obtained is 115 V/µm. Diodes held 29.6 dBm at zero bias and we detected an output voltage...

Field and Thermal Emission Limited Charge Injection in Au–C60–Graphene van der Waals Vertical Heterostructures for Organic Electronics

Jacopo Oswald, Davide Beretta, Michael Stiefel, Roman Furrer, Sebastian Lohde, Dominique Vuillaume, Michel Calame

Among the family of 2D materials, graphene is the ideal candidate as top or interlayer electrode for hybrid van der Waals heterostructures made of organic thin films and 2D materials due to its high conductivity and mobility and its inherent ability of forming neat interfaces without diffusing in...

Pushing Q-band power performances by means of buffer engineering in AlN-GaN HEMTs

Kathia Harrouche, François Grandpierron, Lyes Ben-Hammou, Etienne Okada, F Medjdoub

We report on AlN/GaN HEMT technology for millimetre-wave applications with various buffer architectures. A high carbondoped buffer enables high electron confinement at the expense of trapping effects, which is attributed to the enhanced point defects and dangling bonds when using higher carbon...
