Job description

Organisation The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :

• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.

Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.The CEA is established in ten centers spread throughout FranceReference 2024-33324Position descriptionCategoryEngineering scienceContractInternshipJob titleDevelopment of a 1-6µm optical collection for cathodoluminescence H/FSubjectThe development of infrared imaging systems requires the creation of pixel arrays in structures based on small-gap materials (1-10µm) such as CdZnTe or HgCdTe alloys. Cathodoluminescence is a microspectroscopic technique that can be used to detect the local states present in the gap and thus identify the defects present in the materials of these detectors. This characterisation method is now widely used in the UV-visible range.
The internship involves continuing the development of a 1-6µm detection chain for our cathodoluminescence equipment. It consists of an optical microscope embedded in a secondary electron microscope (SEM), and will therefore allow us to meet these new characterization challenges.
This 4 to 6 month duration internship may eventually continue in the form of a PhD contract that will focus more on using the system developed during the internship to characterize structures for small-gap imagers.Contract duration (months)4-6Job descriptionThe candidate should have a good aptitude for instrumentation and experimental work, and a strong interest in understanding and aligning optical and microscopic systems. Knowledge of the physics of semiconductor materials would be a plus. To carry out these developments, he/she will work closely with experts in infrared and cathodoluminescence detection systems, as well as with the equipment manufacturer.Position locationSiteGrenobleJob locationFrance, Auvergne-Rhône-Alpes, Isère (38)LocationGrenobleCandidate criteriaPrepared diplomaBac+5 – Master 2PhD opportunityOuiRequesterPosition start date01/03/2025
