Atomic resolution interface structure and vertical current injection in highly uniform heterojunctions with bulk GaN
F. Giannazzo, S. E. Panasci, E. Schilirò +11
The integration of two-dimensional with recently attracted significant interest for future electronic/optoelectronic applications. However, the reported studies hav…
Current transport in Ni Schottky barrier on GaN epilayer grown on free standing substrates
Giuseppe Greco, Patrick Fiorenza, Emanuela Schilirò +9
In this paper, the Ni Schottky barrier on GaN epilayer grown on free standing substrates has been characterized. First, transmission electrical microscopy (TEM) images and nanoscal…
A 5.7 THz GaN/AlGaN quantum cascade detector based on polar step quantum wells
Patrick Quach, Arnaud Jollivet, Andrey Babichev +12
We report on a GaN/AlGaN quantum cascade detector operating in the terahertz spectral range. The device was grown by metal organic chemical vapor deposition on a c-sapphire substra…
Analysis of low-threshold optically pumped III-nitride microdisk lasers
Farsane Tabataba-Vakili, Christelle Brimont, Blandine Alloing +11
Low-threshold lasing under pulsed optical pumping is demonstrated at room temperature for III-nitride microdisks with InGaN/GaN quantum wells on Si in the blue spectral range. Thre…
Monolithic integration of ultraviolet microdisk lasers into photonic circuits in a III-nitride-on-silicon platform
Farsane Tabataba-Vakili, Blandine Alloing, Benjamin Damilano +12
Ultraviolet microdisk lasers are integrated monolithically into photonic circuits using a III-nitride on silicon platform with gallium nitride (GaN) as the main waveguiding layer.…
Demonstration of critical coupling in an active III-nitride microdisk photonic circuit on silicon
Farsane Tabataba-Vakili, Laetitia Doyennette, Christelle Brimont +11
On-chip microlaser sources in the blue constitute an important building block for complex integrated photonic circuits on silicon. We have developed photonic circuits operating in…
