401. [Invited] Direct writing of High-TC Josephson Junctions with Focused Helium Ion BEams

Prof. Shane Cybart (UC Riverside)

12/07/2017, 11:00

Invited Oral Presentation

The 1987 discovery of high-TC superconductivity in ceramic materials at temperatures around 90K set off a frenzy of research in the development of high-TC electronics,motivated by the prospects of electronics operating in liquid nitrogen at 77K opposed to 4K liquid helium. Unfortunately, researchers soon discovered that these new materials were much more difficult to process than conventional...

509. Focused Helium Ion Beam Irradiated Josephson Junctions and Arrays

Yuchao Zhou (University of California, Riverside)

Contributed Oral Presentation

We have fabricated Josephson junctions and arrays with a focused helium ion beam from Y-Ba-Cu-O, a high temperature superconductor^*. The Josephson junction is the fundamental building block of most superconducting electronics. Normally the size of a junction is chosen to be less than the Josephson penetration depth (λ_J) ~4 µm, a fundamental length scale for...

537. [Invited] Terahertz emission from the intrinsic Josephson junctions of high-symmetry thermally-managed BSCCO microstrip antennas

Prof. Richard Klemm (University of Central Florida)

12/07/2017, 11:45

Invited Oral Presentation

We study the coherent terahertz emission from the intrinsic Josephson junctions in thermally-managed, high-symmetry, thin microstrip antennas constructed from single crystals of the highly two-dimensional, layered high-temperature superconductor BSCCO. The thin antennas studied are disk[1,2], square[3], and equilateral triangular[4,5] in shape. Upon application of a dc voltage across the...

451. Tunable Broadband Radiation Generated Via Ultrafast Laser Illumination of an Inductively Charged Superconducting Ring

Thomas Bullard (UES Inc - AFRL/RQQM)

12/07/2017, 12:15

Contributed Oral Presentation

It is well established that superconducting materials will emit microwave/terahertz radiation when illuminated with a femtosecond infrared laser pulse. Typically this phenomena is examined by illuminating a voltage biased superconducting thin film bridge. In this investigation an inductively charged superconducting thin film ring is considered. We believe the configuration lends itself to a...
