Origin of the zero-bias conductance peaks observed ubiquitously in high-T-c superconductors
(American Physical Society, 1998)
The midgap surface states predicted previously to exist on non-{n0m} surfaces of d(xa2-xb2-) superconductors (SC's) can be extended to midgap interface states (MIS's), which exist at almost all interface between grains of ...
Impurity-induced local density of states in a d-wave superconductor carrying a supercurrent
(American Physical Society, 2005)
The local density of states (LDOS) and its Fourier component induced by a unitary impurity in a supercurrent-carrying d-wave superconductor are investigated. Both of these quantities possess a reflection symmetry about the ...
