The influence of magnetic vortices motion on the inverse ac Josephson effect in asymmetric arrays
Boris Chesca, Marat Gaifullin, Daniel John +3
We report on the influence a preferential magnetic vortices motion has on the magnitude of the inverse ac Josephson effect (the appearance of dc current Shapiro steps) and the cohe…
Parametric amplification of electromagnetic waves produced by a flux-flow-oscillator made of YBaCuO Josephson junction arrays
Boris Chesca, Daniel John, Marat Gaifullin
We observe parametric amplification of electromagnetic (EM) waves produced by a flux-flow oscillator made of YBa2Cu3O7 Josephson junctions arrays coupled to the resonant modes of a…
The emergence of quantum capacitance in epitaxial graphene
A. Ben Gouider Trabelsi, F. V. Kusmartsev, D. M. Forrester +4
We found an intrinsic redistribution of charge arises between epitaxial graphene, which has intrinsically n-type doping, and an undoped substrate. In particular, we studied in deta…
Local Measurement of Microwave Response with Local Tunneling Spectra Using Near Field Microwave Microscopy
Tadashi Machida, Marat B. Gaifullin, Shuuichi Ooi +3
We have designed and built a near-field scanning microwave microscope, which has been used to measure the local microwave response and the local density-of-states (LDOS) in the are…
Nature of c-axis coupling in underdoped Bi2Sr2CaCu2O8 with varying degrees of disorder
Panayotis Spathis, Sylvain Colson, Feng Yang +7
The dependence of the Josephson Plasma Resonance (JPR) frequency in heavily underdoped Bi2Sr2CaCu2O8+δon temperature and controlled pointlike disorder, introduced by high-energy el…
Role of pair-breaking and phase fluctuations in c-axis tunneling in underdoped BiSrCaCuO
C. J. van der Beek, P. Spathis, S. Colson +4
The Josephson Plasma Resonance is used to study the c-axis supercurrent in the superconducting state of underdoped BiSrCaCuO with varying degrees of contr…
