Welcome to Sungjae Cho’s group in the Physics Department @ KAIST! Our lab studies quantum transport in mesoscopic devices. We explore electronic, spintronic and thermoelectric properties of nanostructured materials such as graphene, topological insulators and transition metal dichalcogenides. Please refer to Research page to learn more. Experiments of charge and spin transport in low-dimensional (≤2D) devices to investigate: quantum electron-dynamics arising from topological phases of matter; quantum phase transitions (QPTs) driven by large modulation of carrier densities; spin dynamics in chalcogenide nanostructures; newly-emerging physical properties and phases in heterostructures
