Epitaxial YBCO HTS Thin Film on SrTiO3 substrate up to 30 mm
MTI Corp joins with several research institutes around the world, to finally make high Tc superconducting epitaxial thin film commercially available at an affordable price. MTI supplies high quality double side epitaxial thin film up to 3" diameter on LaAlO3, LSAT, Al2O3 and SrTiO3 single crystal substrate by a unique technology.
This will make YBCO thin film available at low cost. Researchers don't need to grow thin film any more, but concentrate their talent on HTSC film related devices, such as microwave filter for wireless and HTSC Squid.
