R&D nanofabrication scientist of superconducting single-photon detectors

University of Geneva, Group of Applied Physics - Quantum technologies

The Group of Applied Physics (GAP) Quantum Technologies at University of Geneva, in collaboration with ID Quantique (IDQ), has developed a strong R&D program in the field of Superconducting Nanowire Single-Photon Detectors (SNSPD). The ongoing partners’ mission is to enable scientists and industrial users to create the future of quantum technologies using the best single-photon detectors. This program developed high-performance and commercial-grade SNSPDs with unique specifications. These detectors are now used in state-of-the-art quantum communication experiments, and a technology transfer to IDQ led to a successful commercialisation.
The GAP Quantum Technologies is seeking applications to fill an opening the role of an R&D nanofabrication scientist. Within an Innosuisse project, we aim at developing novel types of SNSPDs with improved performance through nanofabrication process and material development combined with innovative SNSPD designs. The project will be executed in close collaboration with IDQ, which will create synergies towards a commercialisation of the new developments.
The ideal candidate holds a PhD in a relevant physics and/or engineering field. As a forward-looking problem solver, you will be responsible for delivering creative and innovative solutions to complex problems in a collaborative manner. You will be taking initiatives and drive this project towards completion within the defined timeline and scope. Through a sustained and effective communication with all members of team and with external partners, you will ensure that the priorities are set and followed properly. You are interested in the application of R&D to product development.
Location: University of Geneva, Group of Applied Physics – Quantum Technologies. Frequent trips to CMi at EPFL in Lausanne, and regular visits to IDQ in Geneva.
Key functions and responsibilities:
– Lead the R&D and project management activities
– R&D activities: master the physics of SNSPDs, continuously develop/maintain/improve the nanofabrication process and testing tools to achieve the desired objectives, optimise the development cycle, proactively propose new development directions when necessary
– Project management activities: define detailed development plan and set priorities, coordinate with IDQ on a regular basis, execute within defined timeline, communicate clearly with stakeholders and partners, find and nurture external collaborations when necessary
Desired profile and required expertise:
– PhD in physics or engineering with a strong focus on nanofabrication, optoelectronic devices and materials development
– A strong record showing the ability to lead a complex scientific projects with ambitious objectives
– A deep understanding and expertise of the following nanofabrication techniques
– Metalloid thin film (< 10 nm) deposition with sputtering and/or co-sputtering techniques
– Detector design coding with Python or similar
– E-beam lithography
– Optical lithography
– Various physical and wet etching
– SEM, AFM, other metrology techniques
– Ellipsometry (measurements and modelling)
– Numerical simulation of optical interaction of nano-structures.
– Expertise in the development and characterisation of thin superconducting films
– Experience with cryogenics
– SNSPD fabrication and characterisation expertise is highly desired but not mandatory
– A good understanding of RF analog electronics
– A good understanding of single-photon detectors and of quantum optics
– Full fluency in English (written and oral)
Start date and duration: the position is opened immediately, 2-years duration
