Research Interests
Professor Sardashti’s group performs experimental studies on the structure-properties relationships in hybrid superconductor–normal materials systems. The group focuses mostly on tailoring band structures at the heterointerfaces between superconducting and normal (semiconducting, metallic, ferromagnetic) materials. This requires a deep understanding of the mechanisms that control the physics and chemistry of those interfaces. The resulting band-engineered hybrid systems are expected to play a key role in the development of hybrid classical–quantum processors and sensors. The group’s experimental work spans a wide range of disciplines including materials growth & characterization, nanofabrication and low-temperature characterization.
