Zhang Lab
Single atom and molecule level investigation and manipulation.
About Dr. Zhang
Welcome to Yuan Zhang’s research group. We specialize in single atom/molecule level investigations and manipulations using low temperature (77 K, 4.2 K) ultra-high vacuum scanning tunneling microscopy (LT-UHV-STM) and qPlus atomic force microscopy (Q+AFM). More specifically, we investigate and operate various artificial molecular machines such as single molecule motors, unidirectional propellers, rotor networks, and molecular transport devices on material surfaces.
Various 2D materials and molecular systems are also fabricated in situ and characterized by local spectroscopy of STM/Q+AFM in search of novel electrical, magnetic, and mechanical properties. The capability of local chemistry alteration allows direct engineering of material properties at the atomic scale. In addition, by combining synchrotron radiation with traditional STM, we investigate novel magnetism and charge transfer phenomena at buried interfaces and layered heterostructures.
Our research lies in an interdisciplinary field that encompasses condensed matter physics, material science, quantum physics, physical chemistry, and nanoscience.
