11. Shunt-capacitor-assisted synchronization of oscillations in intrinsic Josephson junctions stack

Author

Martin, I., Halasz, Gabor B., Bulaevskii, L.N., and Koshelev, A.E.

Subjects
Josephson junction -- Analysis, Oscillation -- Analysis, Superconductive devices -- Design and construction, Physics
Abstract

A shunt capacitor has stabilized synchronized oscillations in an intrinsic Josephson junction stack biased by a dc current by coupling each Josephson junction to all the other junctions. The shunt has helped to enter the phase-locked regime in the beginning of the oscillations, after switching on the bias current, and it is used to tune radiation power, which has dropped as the shunt capacitance has increased.
