معرفی
Chang Liu is an Assistant Professor at the Department of Economics, Stony Brook University. He specializes in advanced microscopy techniques and nanoscale material characterization, with a focus on plasmonics, 2D materials, and quantum phenomena. His research employs cutting-edge tools like scattering-type scanning near-field optical microscopy (s-SNOM) and terahertz spectroscopy to explore electronic and optical properties at the nanoscale.
His work spans interdisciplinary areas including graphene heterostructures, Dirac materials, and phase transitions in correlated oxides. Liu’s contributions include developing novel imaging modalities (e.g., BOSON) and advancing understanding of polaritonic systems. He collaborates with synchrotron facilities like NSLS-II for ultra-high resolution studies.
Notable research trends include exploring nanoscale structural phase separations, tunable phonon polaritons in van der Waals heterostructures, and nano-photocurrent dynamics in twisted bilayer systems. His technical innovations, such as machine learning for nano-optical data analysis and cryogenic s-SNOM setups, enhance experimental precision.
Liu’s lab is part of the Stony Brook Center for Game Theory, though his direct research themes focus on materials physics. Current projects include roadmap development for 2D material photonics and exploring moiré ferroelectricity in twisted WSe₂ systems.
