Self-consistent solution for proximity effect and Josephson current in ballistic graphene SNS Josephson junctions
Self-consistent solution for proximity effect and Josephson current in ballistic graphene SNS Josephson junctions
We use a tight-binding Bogoliubov--de Gennes (BdG) formalism to self-consistently calculate the proximity effect, Josephson current, and local density of states in ballistic graphene superconductor-normal conductor-superconductor (SNS) Josephson junctions. Both short and long junctions, with respect to the superconducting coherence length, are considered, as well as different doping levels of …
