Abstract

Solving the Bogoliubov-de Gennes equation for a tight-binding mean-field Hamiltonian with local superconducting order parameter, we investigate stable superconducting order parameter structures for anisotropic superconductors in nano-structures. Numerical results show that for a diamond-shaped d-wave superconductor symmetry is mainly s + id-wave, although other components, such as an anisotropic s-wave component, exist.
