Kaihui Liu's group has been long engaged in studying growth mechanism and spectral physics for low-dimensional materials. We independently designed the meter-scale single-crystal manufacturing equipment, built the single nano-object level in-situ optical characterization system and developed two-dimensional material composite fibers for all-fiber integration devices. We have made several important progresses, including (1) realizing surficial and interfacial engineering of the growth of 2D materials; (2) developing global methods of synthesizing meter-sized single-crystal films; (3) fabricating structure-dependent devices. Professor Liu has published more than 100 scientific journals, including correspondence-authored Nature (2), Nature Nanotechnology (2), Nature Photonics (2), Nature Chemistry, Nature Communications (4), Advanced Materials (10), JACS (2), Nano Letters (6), PNAS and Science Bulletin.
