Demonstration of ScAlN/GaN RF HEMTs on silicon substrate

Seif El Whibi, Nagesh Bhat, Yassine Fouzi, N. Defrance, Jean-Claude de Jaeger, Zahia Bougrioua, Florian Bartoli, Maxime Hugues, Yvon Cordier, Marie Lesecq

ScAlN ensures a very high carrier density at the interface with GaN in spite of very thin barrier, which makes it possible a promising barrier layer for HEMTs in view of power switching and RF/mm-wave power amplifier applications. We have demonstrated the feasibility of the growth with ammonia...

Stress and doping analysis of low n-doped GaN layers grown on GaN, silicon and sapphire substrates by micro-Raman 2. Physics and characterization

Ndembi Ignoumba-Ignoumba, Camille Sonneville, Adrien Bidaud, Mohammed El Amrani, Thibaud Guillemin, Maroun Dagher, Vishwajeet Maurya, Florian Bartoli, Eric Frayssinet, Farid Medjdoub, Julien Buckley, Yvon Cordier, Matthew Charles, Dominique Planson, Cyril Buttay

Vertical GaN power devices counters the drawbacks of the lateral ones. The best performances are observed with vertical GaN-on-GaN, but the absence of large GaN substrates makes the homoepitaxy option less marketable than the heteroepitaxy one. However, thick heteroepitaxial GaN drift layers must...
