Grant-in-Aid for Research Activity Start-up
Some material systems are believed to host Majorana zero modes - quantum charge-neutral states with their properties unexplored. Here we develop a Josephson junction with high-quality topological insulator thin films, aiming to observe the signature of Majorana zero modes and control their mysterious quantum states. We succeeded in precisely fabricating sub-micron-sized junctions and performing highly accurate measurements of these devices.
