Electronic theory for scanning tunneling microscopy spectra in bilayer nickelate thin films
The study uses Scanning Tunneling Microscopy (STM) to investigate superconducting gap features in bilayer nickelates. By modeling the system using Wannier functions and a continuum Green’s function approach, researchers can link tip position and impurity effects to the symmetry of the superconducting order parameter, providing methods to distinguish between different pairing symmetries.
