High Breakdown Voltage GaN Schottky Diodes for THz Frequency Multipliers

G. Di Gioia, E. Frayssinet, M. Samnouni, V. Chinni, P. Mondal, J. Treuttel, X. Wallart, M. Zegaoui, Guillaume Ducournau, Yannick Roelens, Yvon Cordier, Mohamed Zaknoune

Quasi-vertical gallium nitride (GaN) Schottky diodes on silicon carbide (SiC) substrates were fabricated for frequency multiplier applications. The epitaxial structure employed had an n− layer of 590 nm with doping 6.6 × 1016 cm−3, while the n+ layer was 950 nm thick, with doping 2 × 1019 cm−3.…

Sub‐Micron thick Step‐Graded AlGaN Buffer on Silicon with a High Buffer Breakdown Field

Elodie Carneiro, Stéphanie Rennesson, Sebastian Tamariz, Kathia Harrouche, Fabrice Semond, Farid Medjdoub

We report on a sub-micron thick AlGaN/GaN high electron mobility transistor (HEMT) epilayers grown on silicon substrate with a state-of-the art vertical buffer breakdown field as high as 6 MV/cm enabling a high transistor breakdown voltage of 250 V for short gate to drain distances despite such a…

Highly Si‐doped GaN regrown by MOVPE for ohmic contact applied to quaternary barrier based HEMT

Charles Pitaval, Cédric Lacam, N. Defrance, Christophe Gaquière, Nicolas Michel, Olivier Parillaud, Sylvain Delage

The quaternary barrier InAlGaN is suitable for GaN HEMT power microwave applications. High doping of semiconductor under the drain and source is a known suitable solution to achieve low ohmic contact resistance. However, InAlGaN quaternary alloys require low thermal budget to avoid indium…
