      abstract     = {The topological superconducting hybrid structures have been
                      attracting considerable research interest in recent years,
                      as they are promising candidates for topologically protected
                      qubits. Because of this, a substantial demand for
                      appropriate superconducting substrates has been created. In
                      our study we explore the superconducting properties of
                      Ir/Nb(110) films. Our focus is on the investigation of the
                      change in the work function and the size of the
                      proximity-induced superconducting gap of Ir overlayers
                      deposited on Nb(110). The work function plays a crucial role
                      in determining the behavior of electrons at the
                      superconducting surface, thereby influencing the charge
                      transport. In the specific context of superconductor hybrid
                      structures for Majoranas, the target is to effectively
                      manage the work function mismatch while maintaining a robust
                      proximity effect through the overlayer. This approach will
                      also provide valuable information for studying the proximity
                      effect in a topological insulator/superconductor(TI/SC)
                      system. Our findings are based on first-principles
                      calculations using the full-potential Korringa-Kohn-Rostoker
                      Green function method and its Kohn-Sham Bogoliubov-de Gennes
                      (KS-BdG) extension to describe superconducting
                      heterostructures [1].We thank the ML4Q (EXC 2004/1 -
