My principal research field is experimental condensed matter physics, and my research group at Caltech currently focuses on scientific and technological topics of correlated electrons (e.g., high-temperature superconductors; novel magnetic systems), topological materials (e.g., topological insulators and superconductors; topological states and channels for quantum information), low-dimensional systems (e.g., van der Waals materials, including graphene, h-BN and two-dimensional transition-metal dichalcogenides; graphene nanostripes; carbon nanotubes; nanoparticles), spintronics (based on strong spin-orbit-coupled materials and half-metallic ferromagnets), nanoscience and nanotechnology (e.g., instrumentation of scanning probe microscopy for nanoscale characterization; nanofabrication of electronic, optoelectronic, valleytronic and spintronic devices; nanoscale strain engineering of graphene and transition-metal dichalcogenides), energy research (e.g., energy storage in supercapacitors and lithium ion batteries, energy conversion in photovoltaic and fuel cells), and precise measurements using superconducting technology.
