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…
Influence of growth parameters on the superconducting transition temperature in granular aluminum films
Aniruddha Deshpande, Jan Pusskeiler, Christian Prange +3
This study investigates the influence of various growth parameters on normal-state resistivity and superconducting transition temperature Tc of granular aluminum films. Specificall…
Interplay of coupling, residual, and quasiparticle losses for the frequency- and temperature-dependent quality factor of superconducting resonators
Elies Ben Achour, Cenk Beydeda, Gabriele Untereiner +2
The overall, loaded quality factor quantifies the loss of energy stored in a resonator. Here we discuss on general grounds how of a planar microwave r…
