Research Abstract

Tunneling spectrum under magnetic field and its in-plane angle dependence would offer a novel way to determine the superconducting gap symmetry in the unconventional superconductors. Development of high quality thin films and devices based on that are highly required. Conditions to make ultra-thin films of the parent compound of iron-based superconductors are established in this work. The gap symmetry of some iron-based superconductors having nodes is also investigated via quasi-particle excitation at low temperatures and their evolution for different scattering levels.
