SrTiO3
The lattice constant (3.905Å) of SrTiO3 fits the common high Tc superconductive material YBCO (3.88 Å) very well. It has twin-less crystal structure and very good physical and mechanical properties for film growth. It is suitable for various high Tc films. It is also suitable for different film growth technologies such as Magnet Sputtering, Pulsed Laser Deposition (PLD), Vapourization, MOCVD, CVD, and laser MBE etc. It is widely use for special optical windows and target.
