Josephson current mediated by ballistic topological states in Bi2Te2.3Se0.7 single nanocrystals

Topological insulators in contact with a superconductor could house unusual physical states such as Majorana fermions. Here, the authors fabricate and report the electron-transport characteristics of Josephson junctions built using a nanoscale topological insulator, finding evidence for ballistic t...
