Abstract:

A fabrication method is proposed for deposition of wide-area, homogenous thin films
of high-Tc, oxide superconductor using a double-pulse, laser-driven, detonation-wave
thruster as the deposition source. The device will use laser ablation of bulk superconductors
followed by detonation-wave processing and hypersonic nozzle expansion of resulting
gases to generate a homogenous atom beam. Films will be deposited on substrates of
sapphire, yttrium-stabilized zirconia, and magnesium oxide. Samples will be characterized
by structural and chemical analysis, DC resistance and magnetoresistance versus temperature,
and AC magnetic susceptibility, using standard techniques.

Potential Commercial Application:

Potential Commercial Applications:  The outcome could be far-infrared detectors and
microwave circuits such as low loss transmission lines and filters having significant
value in communications applications, both military and industrial, as well as in
scientific research.
