Oxide Molecular Beam Epitaxy Group
The first goal of our research is to address some key open questions in the physics of high-temperature superconductors (HTS):
- What is the dimensionality of the HTS phenomenon?
- What are the spin and charge of free carriers?
- What is the nature of the superconducting transition?
- What is the nature of the overdoped metallic state – a Fermi liquid?
- What is the ‘glue’ (the bosons) responsible for electron pairing?
- What is the mechanism of the Giant Proximity Effect (GPE)?
Our approach to this goal is to:
- utilize Molecular Beam Epitaxy (MBE) synthesis to fabricate atomically smooth HTS thin films, multilayers, superlattices, and combinatorial libraries;
- manufacture various HTS devices and nano-structures and study the (magneto)transport and other physical properties in SIN, SIS, and SNS HTS junctions, nanowires, and nanorings;
- study, in collaboration with the Electron Spectroscopy and Scanning Tunneling Microscopy groups, ARPES and STM spectra of various HTS cuprates synthesized by oxide MBE
Our second and ultimate research goal is to discover, or artificially assemble, new and superior HTS materials
