Nanocrystals are used as building blocks for optoelectronic components such as LEDs, solar cells, infrared detectors and cameras. This research activity has a clear focus on infrared materials, in particular PbS and HgTe nanocrystals, but we are also interested in perovskite materials or 2D materials (graphene, WSSe…). Our objectives are twofold: to correlate the electronic structure of confined semiconductors with their transport properties and to fabricate components in particular in the near and mid-infrared. The experimental techniques used are the following: nanoparticle synthesis and component fabrication using the INSP’s glovebox and clean room, absorption (200 nm to 150 µm) and emission (400 nm to 2.5 µm) spectroscopy, low-current electronic transport measurements, photoconduction measurements under cryogenic conditions, characterisation of optoelectronic components.
