Substrates and Wafers for Magnetic and Ferroelectric Film Growth
Strontium Titanate or SrTiO3 (STO) single crystal has a twinless crystal structure and very good physical and mechanical properties for film growth. STO provides a good lattice match to most materials with Perovskite structure. It is an excellent substrate for epitaxial growth of HTSC (High-Temperature Superconductor) and various oxide thin films. Its lattice constant (3.905Å) matches well with the common high TC superconductive material YBCO (lattice constant 3.88 Å). STO is also a suitable platform for other high TC films such as Bi-system, La-system, and others. SrTiO3 single crystal has been utilized for special optical windows and as a high-quality sputtering target as well. It can also accommodate diverse film growth technologies such as Magnet Sputtering, Pulsed Laser Deposition (PLD), Vaporization, MOCVD, CVD, laser MBE, etc. Films made with these materials and technologies on SrTiO3 wafers exhibit excellent performance.
Hangzhou Shalom EO provides stocked standard SrTiO3 (or STO) wafers and customized wafers.
