YBCO Thin Film 500nm ( two sides ) on Al2O3(R-plane), 10x10x0.5 mm

In stock
Item Number: FmYBCOonAl2O3R101005S2FT500nm

Epitaxial YBCO HTS Thin Film Up to 3" ( 75 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 very 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.
