Contactless terahertz mapping of wafer-scale superconducting NbTiN thin films
Yayi Lin, Marc Neis, Marcello Pio Guardascione +9
For large-scale superconducting quantum technology, e.g. quantum computing, the homogeneity of wafer-scale superconducting thin films is vital for consistent performance of the fab…
Signatures of Dynes superconductivity in the THz response of ALD-grown NbN thin films
Frederik Bolle, Yayi Lin, Ozan Saritas +6
The frequency-dependent complex optical conductivity reflects key properties of superconductors, such as the energy gap in the density of states (DOS) and the superfluid density. F…
THz electrodynamics and superconducting energy scales of ZrN thin films
Ozan Saritas, Frederik Bolle, Yayi Lin +5
The terahertz (THz) properties of ZrN thin films grown with CMOS-techniques on industry-standard 300 mm silicon wafers are investigated in order to explore their superconducting be…
Universal relation between residual resistivity and A coefficient in correlated metals
Anna Yu. Efimova, Yohei Saito, Atsushi Kawamoto +3
The effects of strong electronic correlations and disorder are crucial for emergent phenomena such as unconventional superconductivity, metal-insulator transitions, and quantum cri…
Failed superconductivity in a Mott spin liquid material
Yuxin Wang, Vladimir DobrosavljeviÄ, Eun Sang Choi +5
A central challenge for understanding unconventional superconductivity in most strongly correlated electronic materials is their complicated band structure and presence of competin…
