The goal of this project is to develop infrared devices based on nanocrystals and more particularly a focal plane array operating in the SWIR range (1-2.5 µm). The applicants will be involved at all step of the device fabrication from nanocrystal processing to focal plane array characterization, including clean room processing and basic device characterization.
This project will be conducted in interaction with the INSP teams (student of the group, chemical engineer, clean room) but also with the company NIT which will provide the read-out circuits.
* Manufacture of the component by combining clean room techniques (optical and laser litho, metal and dielectric deposition) and glove box manufacturing. The nanoparticles will be synthesized by the team's chemical engineer
* Characterization of the component by measurements of electronic transport in cryogenic condition. This also includes time-resolved current photo measurements.
* Fabrication of a camera demonstrator by coupling reading circuit and film of nanocrystals
The candidate will have a strong background in semiconductor physics. Experience in one of the following areas is desirable: clean room manufacturing, measurement of electronic transport in cryogenic conditions, handling of colloidal nanocrystals, experience with read out circuit. The ideal profile would be a candidate with a thesis on optoelectronics of nanocrystals. It is essential to have published scientific paper to apply. The candidate must have a strong appetite for experimental work (development of new instruments and measurement of characterization). The project is also very multidisciplinary with chemistry, physics of µ-fabrication and instrumentation. You don't have to be an expert on every subject, but be ready to learn on all aspect of the project. The candidate will have to work in an international team and therefore fluency in English is required.
This project is part of the ERC BlackQD and ANR NITquantum projects which focus on the study of infrared nanocrystals and their integration into components The work will be carried out at the “Institut des Nanosciences de Paris” (INSP) in the team of Emmanuel Lhuillier. The work will be done in collaboration with the chemical engineer of the laboratory, the cleanroom engineers of the INSP and also the other students of the team.
