Abstract:
A method for forming SrTiO3/BaTiO3 artificial super lattices on a silicon substrate by using a TiN buffer layer is provided to enhance crystallization and dielectric characteristics by alternatively depositing a SrTiO3 thin film and a BaTiO3 thin film on the substrate. A silicon substrate is inputted in a chamber of a pulse laser depositing apparatus, and then a TiN buffer layer is deposited on the silicon substrate with the TiN buffer layer at a temperature of 650 to 750°C. A SrTiO3 thin film and a BaTiO3 thin film are alternatively deposited on the silicon substrate at a temperature of 300 to 750°C to form artificial super lattices.
