Attempting to predict, realize, and deploy quantum materials will include advanced synthesis and novel characterization for high-speed and energy-efficient device applications, and these interdisciplinary efforts for accelerating materials development will identify three goals to expand the impact of our novel approach and research expertise:
- Atomic-scale synthesis/processing: materials on demand in novel thin film heterostructure design
- Nanoscale characterization: properties on demand in hybrid quantum solids
- Materials innovation platforms: functionalities on demand in advanced semiconductor/quantum devices
Kang group is eager to leverage interdisciplinary research on both fundamental materials physics, and advanced materials engineering to understand and deploy processing-structure-properties relationships in quantum materials. Our approach has broadened to include every class of materials such semiconductors, superconductors,topological materials, and nanomaterials, which are used to advance understanding in a variety of research areas e.g., information nanotechnology, energy application, and quantum science. For this, detailed information (keywords, purpose) is shown below.
“Atomic-scale materials synthesis & processing promotes quantum properties and novel functionalities”
- Atomic layer-resolved heterostructures & superlattices
- Low dimensional epitaxy of semiconductor & quantum materials
- Functional nano-integrated interfaces in hybrid heterostructures
- Multi-dimensional van der Waals materials synthesis and their freestanding membranes
- Our main goal is to fabricate thin film quantum materials with atomic precision. Crystal structures, composition, and defects are atomically controlled to push materials properties to the ultimate thickness limit, which include conducting graphene, insulating hBN, semiconducting transition metal dichalcogenides, semi-metal/superconducting Fe-based compounds, and ferroelectric/ferromagnetic a few-atom-thick perovskite oxide layers.
- Another goal is to explore unprecedented materials properties by heterostructure design with nanoscale dimension and geometry. Atomic-resolution diffraction/imaging, angle-resolved/time-resolved spectroscopy, and low temperature electromagnetic transport measurement will prove local atomic configuration, phase transition, and topological edge states.
- The final goal is to govern electronic, optical, and magnetic properties for sensing, switching, and modulating applications. Highly sensitive, ultrafast, low power switching devices will be demonstrated, including high mobility electronics and novel spintronic devices.
