Novel electronic states emerge in nanostructures due to the reduced dimensionality, making nanostructures unique material platforms for fundamental science. For example, topological nanomaterials induce electronic properties that cannot be found in bulk crystals or thin films, such as the 3D quantum Hall states observed in nanoslabs of topological semimetals and Majorana bound states observed in nanowires of topological superconductors. However, current synthesis techniques do not allow precise control over the morphology and dimensions of the nanostructures, severely limiting their use for quantum science.
As a pioneer in synthesis of topological nanomaterials over the past ten years, Dr. Cha advances chemical vapor deposition (CVD) and develops novel fabrication methods to synthesize nanostructures of quantum materials whose size, morphology and crystalline quality will be precisely controlled. The overarching goal is to transform the precision of nanomaterial synthesis for quantum materials.
Dr. Cha is an associate professor in the Department of Mechanical Engineering and Materials Science at Yale University. She received her PhD from Cornell University.
