Substrates for thin film applications
TiO2(Rutile)Substrate
 
 

We supply rutile substrates which are suitable for the epitaxial growth.
Varieties of substrate are not only normal type but also conductive type and step-surface type. We hope that will help your research and development.
 
  　High quality material.
　We can supply Nb doped crystal (conductive substrates).
　We offer STEP substrate with ultra-precise surface.
