Strontium Titanate or SrTiO3 (STO) single crystal provides a good lattice match to most materials with Perovskite structure. It is an excellent substrate for epitaxial growth of HTS and many oxide thin films. Its lattice constant (3.905Å) 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 such as YBCO, Bi-system, La-system and others. SrTiO3 is an excellent and wide applied High Tc superconductive single crystalline substrate. SrTiO3 single crystal has also been used widely for special optical windows and as high quality sputtering target. It is also suitable for different film growth technologies such as Magnet Sputtering, Pulsed Laser Deposition (PLD), Vapourization, MOCVD, CVD, and laser MBE etc. Films made by these materials and technologies on SrTiO3 wafers have excellent performance, for instance Tc>90K, Jc> = 106A/cm2.
Hangzhou Shalom EO provides not only the stocked standard epi-ready SrTiO3 (or STO) wafers, but also the custom type wafers upon request.
