I am currently a PhD candidate at Université de Sherbrooke Working on low temperature quantum materials. I work under supervision of prof Patrick Fournier and under the advisement of Prof Louis Taillefer and Prof Claude Bourbonnais . As my PhD project, I work on Little Parks effect.
This project involves the measurement of the charge q of the supercurrent carriers in unconventional superconductors, more specifically the electron-doped cuprates. The Little- Parks experiment measures the resistance of a nanoring close to its transition temperature as a function of applied magnetic field. It is used to detect resistance oscillations as a function of the magnetic field with a single field period set by the size of the ring and the charge of the supercurrent carriers. For conventional superconductors, the charge is always q = -2e for the electron pairs. However, there are theoretical models predicting different values for superconducting copper-oxygen materials (cuprates) in different doping regimes. Up to now, at optimal doping with the maximum critical temperature, the existing measurements with YBa2Cu3O7 nanorings have also shown q = -2e. Since our expertise lies rather in Pr2-xCexCuO4, the electron-doped cuprates, we propose to explore the Little-Parks effect on this material as a function of doping. During my PhD journey I worked with many different devices such as PPMS, PLD, SQUID, AFM, XRD, Photolithography and RF sputtering.
