Offer Description
This topic concerns the study, at very low temperatures (<100 mK), of the quantum transport properties of silicon-based superconducting transistors.
This PhD project focuses on the investigation, at very low temperature, of CMOS silicon transistors for which the source and drain contacts are superconducting. The main goal is to study their electronic properties and to evidence the contribution of the superconductivity in their response.
This thesis aims at:
- finding conditions for which superconducting correlations propagate in the silicon channel and for the shortest devices
- showing the appearance of a tunable supercurrent (Josephson effect)
- contributing to pave the way towards the development of new superconducting quantum devices that are suitable for quantum information in a fully scalable technology
Various materials will be integrated such as silicides (mostly CoSi2) and superconducting boron doped silicon (Si:B) obtained by laser annealing. The careful analysis of the obtained results will allow the precise characterization of the contact resistance at the S/D contacts and of superconducting proximity effect in the silicon channel. Once this results established, the project will focus on more complex geometries such as superconducting qubits (gatemon’s – gate tunable transmon’s) embedding on-chip capacitors and superconducting resonators.
The devices will be manufactured in collaboration with the LETI and STmicroelectronics. The process flow has been already established and some devices are under current fabrication. The project benefits from a dedicated mask set designed in a previous project and from previous studies on silicides and Si:B that allow us to step up the fabrication of superconducting transistors in 300 mm.
