‘Effects of high temperature on the electrical behaviour of AlGaN/GaN HEMTs’

Y. Guhel, B. Boudart, Virginie Hoel, M. Werquin, Christophe Gaquière, Jean-Claude de Jaeger, M. A. Poisson, I. Daumiller, E. Kohn

High-temperature effects on the electrical behavior of AlGaN/GaN HEMTs have been evaluated. dc measurements have been performed for different illumination and temperature conditions. The unpassivated devices present a good ohmic contact technology up to 550 °C in air. These high-temperature…

Raman characterization of Ar+ ion-implanted GaN

B. Boudart, Y. Guhel, J. C. Pesant, P. Dhamelincourt, M. A. Poisson

Ar+ ions were implanted at room temperature in n-type hexagonal GaN for device isolation purpose. We performed electrical measurements and resonance Raman spectroscopy in order to monitor the electrical and structural changes of non-annealed and annealed implanted GaN samples. On increasing the…
