Substrates for Superconductor Thin Films
Marketech
offers the widest range of products for the high temperature
superconductor field. These range from basic HTSc raw materials,
substrates, powders, targets, as well as finished parts that include
current leads, shields, tubes, and thin films.
Single
crystal substrates are available for deposition of a wide range of
superconductor compounds. Special prepared SUPERSURFACE substrates with
extrodinatry low roughness are available as well as large substrates.
Special sizes, edge orientation, custom and off axis orientations are
avaialble in some compounds and can be prepared at a reasonable price.
