@article{Fu2008SuperconductingPE, title={Superconducting proximity effect and majorana fermions at the surface of a topological insulator.}, author={Liang Fu and C. L. Kane}, journal={Physical review letters}, year={2008}, volume={100 9}, pages={ 096407 } }

We study the proximity effect between an s-wave superconductor and the surface states of a strong topological insulator. The resulting two-dimensional state resembles a spinless px+ipy superconductor, but does not break time reversal symmetry. This state supports Majorana bound states at vortices. We show that linear junctions between superconductors mediated by the topological insulator form a nonchiral one-dimensional wire for Majorana fermions, and that circuits formed from these junctions… Expand
