Description of the thesis topic
The PhD student will be in charge of fabricating diamond finger field effect transistor (FinFET) components using the means available at the Néel Institute (NanoFab clean room and those of the SC2G team). He will rely on the partners of the ANR LSD MOSFET project for the design of the components (LAPLACE/TOULOUSE) and the fabrication of the epitaxies (DiamFab/GRENOBLE). He will have to develop a surface preparation process to ensure the proper functioning of finger FET transistors with an accumulation regime on the wire walls. For this, he will rely on the characterization means and the know-how of the laboratory to describe the physical mechanisms at play at the interface (IV, CV, admittance spectroscopy, Hall effect, deep level transient spectroscopy...). The candidate will have to set up the physical models necessary to describe the electronic transport in transistors. He will publish results in journals and present them at national and international conferences in the field. He will also present the results during the project meetings.
The person recruited should have a solid knowledge of solid-state physics and in particular the physics of semiconductors and electronic components. As an experimenter, he will be required to undergo training in order to become autonomous in clean room manufacturing processes (lithography, etching, metal deposition, etc.). He will have to learn how to use the relevant characterization devices for the study according to the progress of the project: IV, CV, admittance spectroscopy, Hall effect, photo-excitation, deep level transient spectroscopy... Able to communicate on a daily basis with his/her collaborators (Nanofab staff, PhD students, colleagues of the ANR project and PhD supervisor), he will also have to be able to communicate orally and in writing in English in order to valorize his work and to explain his results. The person recruited should have a spirit of synthesis, know how to make available the specific data of his experiments and possess a work ethic.
The scientific activities of the laboratory cover a wide field: superconductivity, quantum fluids, new materials, crystallography, surface science, quantum nanoelectronics, nano-mechanics, non-linear and quantum optics, spintronics, magnetism. In order to reach a critical size to address competitive topics, the 450 members of the laboratory are grouped into research teams and technology support groups according to their common goals of sharing, concerns, expertise. The host team, Wide Band Gap Semiconductors, is composed of 6 permanent staff and about ten PhD and Master students. This team works mainly on wide bandgap semiconductors (GaN, ZnO) and even ultra-wide bandgap semiconductors (diamond, AlN, Ga2O3). With more than 30 years of experience in diamond materials, this team is one of the leading teams in the field of diamond electronic component manufacturing. For this thesis work, the student will interact with all the members of the team and the ANR project and will be guided by his thesis supervisor. All the equipment necessary to carry out the work is already in place, but a significant experimental effort is required to achieve the objectives of the project.
The Institut NEEL is a CNRS laboratory. CNRS is a public, scientific and technological organisation.
The core mandate is to identify, carry out ou have carried out, either alone or with partners, all research that advances science or contributes to the country's economic, social, and cultural progress. Internationally recognised for the excellence of its scientific research, the CNRS is a reference in the world of research and development, as well as for the general public.
