Superconductor
SINGLE CRYSTALS - SUPERCONDUCTORS
Substrates for Superconductor Thin Films
Marketech offers a wide 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.
