Single Crystals
Substrates for Superconductor 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.
