In this project we will work on fabricating quantum dot – superconductor – quantum dot devices to realize a so-called Kitaev chain. In these devices the coupling between the dots should be tunable and is expected to allow for a topological regime where Majorana zero modes exist. Such devices have already been realized with a different material base (InSbAs 2DEGs) where crucial ingredients needed to realize a Kitaev chain have been demonstrated. For this project, we use high quality InAs 2DEGs interfaced with epitaxial Al (superconductor). The candidate will co-design and develop a robust recipe for controllable and reproduceable fabrication of Kitaev-2 and Kitaev-3 devices in the InAs 2DEG, and also perform basic electrical characterizations at 4 K. For this project the candidate will work in the Kavli cleanroom and on various tools including electron beam lithography, chemical etching, metal and dielectric deposition, and scanning electron microscopy. This student project will be an internship with a duration of 3-4 months on the topic of quantum devices.
