Invited Oral

The AC conduction of superconducting heterostructures of SmB6/YB6 are investigated via time domain terahertz spectroscopy[1]. A two-channel model of thickness-dependent bulk states and thickness-independent surface states accurately describes the measured conductance of bare SmB6 thin films, demonstrating the presence of surface states in SmB6. While the observed reductions in the...

509. M1Or2D-02: [Invited] Superconductivity beyond the Pauli limit tuned by locally enhanced Landé g-factor in Au(111)-superconductor heterostructures

Invited Oral

In this work, we report unconventional superconducting properties of high quality Au(111)/Nb heterostructure samples. We carry out tunneling studies in Au(111) using planar tunneling devices with a highly transparent barrier, which enhances the energy resolution of tunneling spectroscopy and allows us to observe and analyze fine in-gap states. We show a locally enhanced Zeeman field due to a...
