OVERVIEW

The IMiNa RG is dedicated to the development of new sensing solutions based on silicon and flexible substrates sensors and their integration into functional prototypes.
We are looking for a self-motivated Junior Research Fellow to join our team in the optimisation of thin-film pyroelectric materials deposition and their application in compact chip-scale devices, in the scope of the EAGER project.
SR&TD project specifications: INL participates in the EAGER project funded by National Funds through the Foundation for Science and Technology (FCT):
(a) Name of the project: EAGER: pyroElectricAlly GEneRated electrons for chips-scale devices
(b) Reference number: Ref. 2022.15666.UTA
(c) Description: This project aims to develop pyroelectrically generated electron sources for chip-scale applications. The exploration of this novel miniature chip-scale device has a wide range of applications in semiconductor industries (vacuum systems) and residual gas sensing applications. The results from this project can lead to several other product developments such as electron beam-assisted multi-gas sensing platforms, chip scale quantum sensors/clocks, and cathode luminescence-based ultraviolet (UV) emission for applications in disinfection, water purification and ionization sources for mass spectrometers, etc.
(d) Scientific Area: Nanomaterials for new markets, thin-films
