Thermal relaxation in metal films limited by diffuson lattice excitations of amorphous substrates
E. M. Baeva, N. A. Titova, L. Veyrat +5
Here we examine the role of the amorphous insulating substrate in the thermal relaxation in thin NbN, InO, and Au/Ni films at temperatures above 5 K. The studied samples are ma…
Deficiency of the scaling collapse as an indicator of a superconductor-insulator quantum phase transition
Andrey Rogachev, Benjamin Sacépé
Finite-size scaling analysis is a well-accepted method for identification and characterization of quantum phase transitions (QPTs) in superconducting, magnetic and insulating syste…
Ionic liquid gating of InAs nanowire-based field effect transistors
Johanna Lieb, Valeria Demontis, Daniele Ercolani +6
We report the operation of a field-effect transistor based on a single InAs nanowire gated by an ionic liquid. Liquid gating yields very efficient carrier modulation with a transco…
Interplay Between Electron Over-Heating and ac Josephson Effect
Alessandro De Cecco, Kévin Le Calvez, Benjamin Sacépé +2
We study the response of high-critical current proximity Josephson junctions to a microwave excitation. Electron over-heating in such devices is known to create hysteretic dc volta…
Collapse of superconductivity in a hybrid tin-graphene Josephson junction array
Zheng Han, Adrien Allain, Hadi Arjmandi-Tash +4
When a Josephson junction array is built with hybrid superconductor/metal/superconductor junctions, a quantum phase transition from a superconducting to a two-dimensional (2D) meta…
Ripples and Charge Puddles in Graphene on a Metallic Substrate
S. C. Martin, S. Samaddar, B. Sacépé +6
Graphene on a dielectric substrate exhibits spatial doping inhomogeneities, forming electron-hole puddles. Understanding and controlling the latter is of crucial importance for unr…
