High temperature superconductivity
Abstract
The overall goals are to develop the technology of Molecular Beam Epitaxy (MBE) growth of HTSC material, to optimize the performance of High Temperature SuperConducting (HTSC) films with high transition temperatures and critical current densities, and to explore the development of electronic devices based on such material. The recently developed MBE system is functioning well, and superconducting films with T sub c's above 77 K are now routinely being grown, in-situ, by atomic layer epitaxy on both MgO and SrTiO3. Work is continuing on understanding such issues as required stoichiometric control and methods of improving kinetic control precision, oxidation capacities of reactive oxygen sources, and the effect of crystallographic quality on superconducting properties.
