A new method for point tunneling into superconductors
Abstract
A novel point tunneling technique for superconductors is reported. This technique employs the intrinsic barrier layer formed between a degenerate GaAs point and the superconducting metal surface. Excellent agreement between theoretical and experimental conductance curves is obtained for polycrystalline lead. © 1967 The American Institute of Physics.
