I am a physics student from ENS school in Paris. For the second semester of my M1, I had to perform a research internship in a foreign country. Hashisaka-sensei kindly accepted me in his lab in ISSP, for a 5.5-month internship.
I am very grateful to all the members of Hashisaka-lab and ISSP for their kindness, for their hospitality and for the time they spent teaching me physics and more. I am particularly thankful for the valuable financial help they provided me by taking in charge the travel and accommodation expenses.
This internship allowed me to explore various aspects of the study of condensed matter systems using mesoscopic devices among which I would like to highlight 3 activities. First, I experienced the device fabrication with Itishree who was studying stacking faults in RuCl3 crystal. Second, I tested a sample holder for a dilution fridge by performing DC transport measurements on High Mobility Electron Transistors and Quantum Point Contacts. Third, I learned about the remote control of instrumentation by working with a homemade Python interface based on the Python QCoDeS library.
This internship was very instructive. I discovered common fabrication and measurement techniques for condensed matter systems. I could also apply theoretical knowledge from my solid state physics classes on real problems. Finally, I feel like I gained a lot of autonomy by preparing and performing the DC measurements almost from scratch.
