Topic:

The aim of this project is to advance the development of nanowire single-photon detectors (SNSPDs) based on cuprates high-Tc superconducting films. These novel sensing devices will take advantage of the high critical magnetic field and temperature of YBCO to expand their capabilities and performance. The successful candidate will (i) Fabricate arrays of high-quality nanowires made of c-axis YBCO thin films. The YBCO film will be electrically characterized in a Physical property measurement system (PPMS). (ii) Characterize the optoelectronic response of these nanowires and demonstrate single-photon detection (SPD) in YBCO. The photodetection performance (efficiency, response time, sensitivity) of the nanowires will be measured using a cryogenic optical setup. (iii) Explore the potential of a-axis YBCO thin films for single-photon detection. The aim is to understand the effect that the crystal axis of the nanowire in order to maximize the performance of YBCO nanowires for SNSPD applications.

Supervision & work environment:
This postdoctoral intenship will be supervised by UdeS experts in growth, and characterization of new quantum materials, Profs Mathieu Massicotte and Patrick Fournier. The work will be done mainly at the Institut Quantique (IQ) and occasionally at the Interdisciplinary Institute for Technological Innovation (3IT). The intern will thus benefit from a highly interdisciplinary research environment that combines students, technicians and professors working together to develop the technologies of the future.
