Nanoscale Impurity Structures on the Surface of $d_{x^2-y^2}$-wave Superconductors

Nikolaos A. Stavropoulos, Dirk K. Morr

We study the effects of nanoscale impurity structures on the local electronic structure of $d_{x^2-y^2}$-wave superconductors. We show that the interplay between the momentum depen…
