Job title

Development of a 1-6µm optical collection for cathodoluminescence H/F

Subject

The 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)

4-6

Job description

The 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.
