We are an experimental research group in condensed matter physics and chemical physics. Using the uniquely designed scanning probe microscopes, we investigate the electronic, vibrational, magnetic, and optical properties of single molecules and low-dimensional materials, as well as the related ultrafast dynamics processes.
Research Interests
1. H-bonding structure and dynamics of interfacial water. 2. Atomic-scale ultrafast dynamics. 3. Nanoscale quantum sensing. 4. Light-element quantum materials.
Nanoscale one-dimensional close packing of interfacial alkali ions driven by water-mediated attraction
The permeability and selectivity of biological and artificial ion channels correlate with the specific hydration structure of single ions. However, fundamental understanding of the effect of ion–ion interaction remains elusive. Here, via non-contact atomic force microscopy measurements... Nature Nanotechnology (2023).PKUPhy news.
Visualizing Eigen/Zundel cations and their interconversion in monolayer water on metal surfaces
Hydrated protons play a critical role in numerous physical and chemical processes. However, their atomic-level characterization remains experimentally challenging, especially for interfacial systems. Using qPlus-based atomic force microscopy and path integral molecular dynamics... Science 377(6603) 315-319 (2022).PKU news, PKU news(English version), Zhishe News.
Surface coordination layer passivates oxidation of copper
Owing to its high thermal and electrical conductivities, its ductility and its overall non-toxicity, copper is widely used in daily applications and in industry, particularly in anti-oxidation technologies. However, many widespread anti-oxidation techniques, such as alloying and electroplating, often degrade some physical properties... Nature 586(7829) 390-394 (2020).PKU news.
Atomic imaging of the edge structure and growth of a two-dimensional hexagonal ice We report that noncontact atomic-force microscopy with a CO-terminated tip enables real-space imaging of the edge structures of 2D bilayer hexagonal ice grown on a Au(111) surface. We find that armchair-type edges coexist with the zigzag edges usually observed in 2D hexagonal crystals... Nature 577 60-63 (2020).PKU news, Physics World, PKU news (English version).
