Josephson penetration depth in coplanar junctions based on 2D materials
Tianyi Li, John C Gallop, Ling Hao +1
Josephson junctions and SQUIDs with graphene or other 2D materials as the weak link between superconductors have become a hot topic of research in recent years, with respect to bot…
Ballistic Josephson junctions based on CVD graphene
Tianyi Li, John Gallop, Ling Hao +1
Josephson junctions with graphene as the weak link between superconductors have been intensely studied in recent years, with respect to both fundamental physics and potential appli…
Non-contact method for measurement of the microwave conductivity of graphene
L Hao, J Gallop, S Goniszewski +4
We report a non-contact method for conductivity and sheet resistance measurements of graphene samples using a high Q microwave dielectric resonator perturbation technique, with the…
Direct measurement of penetration length in ultra-thin and/or mesoscopic superconducting structures
L. Hao, J. C. Macfarlane, J. C. Gallop +1
We describe a method for direct measurement of the magnetic penetration length in thin (10 - 100 nm) superconducting structures having overall dimensions in the range 1 to 100 micr…
Degenerate ground state and anomalous flux hysteresis in an YBa2Cu3O7 grain boundary r.f. SQUID
C. H. Gardiner, R. A. M. Lee, J. C. Gallop +3
We report measurements of the flux hysteresis curves and trapped flux distribution in an YBa2Cu3O7 r.f. SQUID containing two closely spaced grain boundary Josephson junctions in pa…
Microwave intermodulation distortion of MgB2 thin films
G. Lamura, A. J. Purnell, L. F. Cohen +6
The two tone intermodulation arising in MgB2 thin films deposited in-situ by planar magnetron sputtering on sapphire substrates is studied. Samples are characterised using an open-…
