Yan, XZ; Zhao, HW; Hu, Chia-Ren. (American Physical Society, 2000)On the basis of the Keldysh method of nonequilibrium systems, we develop a theory of electron tunneling in normal-metal-superconductor junctions. By using the tunneling Hamiltonian model (being appropriate for the tight-binding ...

Zhao, HW; Hu, Chia-Ren. (American Physical Society, 2000)We study the local single-particle tunneling characteristics [as observed with scanning tunnel microscopy (STM)] for N-D and S-D tunneling, where D is a d-wave superconductor with a {100}{110} grain boundary. The tunneling ...
