The goal of our research is to address some key open questions in HTS physics:
- 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 role of charge stripes (if any) in the HTS state?
- 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 transport and other physical properties in
- SIN, SIS, and SNS HTS junctions;
- HTS nanolayers, nanowires, nanorings and nanodots; and
- combinatorial libraries of overdoped HTS films (in the quest for purported Quantum Critical Points).
