Preparation of the Superconductor Substrate: Strontium Titanate

Abstract : Preparation of the superconductor substrate, strontium titanate, is described. Procedures used to prepare the substrates for the strontium titanate boules are detailed. The strontium titanate crystals are grown using an oxidizing flame (hydrogen to oxygen ratio of 1). The other parameters used for crystals growth are reported. The growth direction was determined to be 5 degrees away from the (211) direction. ICP-emission spectroscopy indicates that the burner material may contribute a small amount of impurities to the crystals. Superconductors, Strontium titanate, Substrates.
