Davide Priante obtained his Ph.D. and Master's degree in Electrical Engineering under the supervision of Professor Boon Ooi at King Abdullah University of Science and Technology (KAUST). Davide received his B.Sc. degree in Material Science Engineering from the University of Padova, Italy, in 2013. He joined KAUST in February 2014 as an M.S. to a Ph.D. student in Photonics Laboratory in the Computer, Electrical, and Mathematical Sciences & Engineering (CEMSE) Division. He received his MSc degree in August 2015 with a thesis based on the recombination mechanism of CH3NH3PbBr3 perovskite. Davide is a member of OSA and SPIE and he also served as a reviewer for the Journal of Nanophotonics and the Journal of Photonics for Energy. Currently, Davide is working as a Postdoctoral Fellow at The University of New Mexico​, United States of America.

Ph.D. thesis project: Study of AlGaN nanowires light-emitting diodes

• Demonstrated 10X enhancement optical power in UV AlGaN LEDs by developing a metal bilayer template that enables higher injection current and heat dissipation.

• Optimized the structure design of UV AlGaN/GaN LEDs on foundry-compatible silicon substrates for improved output power by employing graded structures.

• Analyzed the stability/reliability and the mechanisms involved in UV AlGaN LEDs degradation.

• As a consequence of AlGaN LED degradation study: studied the junction temperature of such devices grown on metal and silicon substrated.

• Improved injection efficiency by 15% of AlGaN LEDs.

• Demonstrated solar-blind AlGaN photodetector grown on metal/silicon substrate.

Research Interests

Davide's research interests included Wide band-gap semiconductor Optoelectronic devices and Nanofabrication processes. His research topic focused on enhancing the performance of large bandgap ultraviolet III-nitride semiconductor nanostructured light emitters. It involved the device structure design optimization and the usage of highly conductive thin metal substrates.
