First PhD defended!

Zhaoen Su (PhD 2017) is the first member of our group. Literally, he started in the summer of 2012 before I arrived to Pittsburgh. Together with others from the first cohort he built our research program from scratch – an empty room for a lab, and no cleanroom process for device fabrication.

Zhaoen first focused on Ge/Si nanowire devices. Through hard work he made great progress and achieved supercurrents and tunable double quantum dots. Facing an uphill battle with charge instabilities, he decided to transpose his project to InSb wires. He got excited about quantum dots coupled to superconducting contacts and realized Andreev molecules, which we have already written up. As Zhaoen begins his new position in the Bay Area, there are still 2 exciting experiments that he has performed waiting to be published.


You can see him holding a mini Cathedral of Learning in the gif above. Congratulations, Zhaoen, and good luck in Silicon Valley!
