Substrates for thin film applications
Strontium Titanate (SrTiO3) substrate
 
 
We provide SrTiO3 single crystal substrates suitable for epitaxial growth. Please use our substrates for your research.
 
   We grow single crystals and manufacture substrates from start to finish.
 High quality and high purity.
 Free surface scratch and hided scratch.
 We can provide STEP SrTiO3 substrates.
 We can provide Nb doped SrTiO3 substrates.
