Abstract:

This project utilizes key empirical principles based on known high-temperature superconductors in order to design and fabricate novel heterostructures that exhibit high-temperature superconductivity. Design of heterostructures is accomplished using the predictive capabilities of ab initio density functional theory DFT calculations combined with many-body theories of electronic structure, such as dynamical mean field theory DMFT. Fabrication is accomplished with atomic-layer control by oxide molecular beam epitaxy MBE synthesis. Finally, the theoretically derived physical and electronic structures are tested using a variety of microscopic and macroscopic characterization techniques. Our approach to the design of the heterostructures is based on emulating key common properties exhibited by the cuprate family of high-temperature superconductors.
