TiO2 Crystal Substrates Rutile or Anatase

TiO2 comes in 2 main forms Rutile and Anatase. Rutile is the most common and also the one which can readily be made into single crystals for use as a substrate for thin film deposition.

TiO2 Crystal Substrates and stabilizing VO2

TiO2 is commonly used for stabilizing VO2 thin films; a form of vanadium oxide which is relatively difficult to grow otherwise. It has a relatively narrow band of growth conditions to avoid V2O3 and V2O5. Furthermore the strain created between the 2 can be used to tune the metal-insulator transition in VO2.
