In-plane topological p-n junction in the three-dimensional topological insulator Bi2−xSbxTe3−ySey
Dirac cone surface states rectify an ultralow dissipative spin and charge current, but it is yet to be confirmed in devices. Here, Tuet al. observe p-type electrical transport on one half surface and n-type on the other in Bi2−xSbxTe3−ySeythin films, realizing a topological p-n junction.
