In the framework of the research project “Innovative systems and services for transport and production” IDEX/I-SITE CAP 20-25 (Challenge 2) and the LabEx IMobS3, Institut Pascal laboratory is offering a 3-year PhD grant for highly motivated candidates interested in completing a PhD thesis in physics.
Hydride Vapor Phase Epitaxy (HVPE) of (In,Ga)N nanowires
for solar cells and micro-LEDs
This tripartite project goal is first to control the development of the InGaN nanowires to homogeneous and controlled composition along the entire nanowire and on the full surface of the substrate by hydride vapor phase epitaxy (HVPE). Secondly, it aims to control their integration in the third generation solar cells and RGB LED devices, breakthrough innovation essential for the next generation of light sources and high-resolution displays. These innovative materials will be tomorrow the essential bricks for energy conversion, new light sources as well as components for nanophotonics, communications and the autonomy of many applications.
The work revolves around the following three key words : growth, modeling and devices, each being linked to the specificities of the three partners of the project: (i) the Institut Pascal has the expertise of the growth of nitride nanowires by the HVPE process, (ii) Pr Dubrovskii is an expert in modeling the nanowires growth mechanisms, to achieve the experimental goal more effectively, (iii) the Pr Amano’s laboratory is world leader in the field of nitrides based devices.
The PhD student must therefore perform and study the growth of nanowires by HVPE, in the Institut Pascal, based on models developed by and with Pr Dubovskii who will stay once a year in the IP. The PhD student will regularly stay in the laboratory of Pr Amano in Nagoya to make and characterize the HVPE nanowires based devices. Collaborations with these two reputable scientists are in place for several years and have already resulted in joint publications.
Thesis Director: Professor Agnès Trassoudaine
Laboratory of attachment: Institut Pascal, Université Clermont Auvergne
Foreign co-supervisors: Professor Hiroshi Amano, CIRFE - IMaSS Nagoya (Japan), and Professor Vladimir G. Dubrovskii, Laboratory of Physics of Nanostructures St. Petersburg Academic University, Ioffe Institute, St. Petersburg State University ITMO University (Russia)
Pr Amano won the Physics Nobel Prize in 2014 for the discovery of the blue LED based on gallium nitride. He is an expert in the field of nitrides materials and their applications. Since 2016, he stayed once a year in the Institut Pascal and sustainable collaboration was born.
Pr Dubrovskii is recognized for his expertise in the modelling of growth mechanisms of semiconductors nanostructures and nanowires. Since 2003, he works with more than 40 groups in 18 different countries including the Institut Pascal at Clermont-Ferrand, in which he stays once a year.
