About Heading link

Our group focuses on applying scanning probe-based nanotechnology in nanomaterials design and properties investigation. We are developing a hybrid analytical technique, which combines nanoimaging and nanospectroscopy, to harvest the angstrom resolution topographic information and chemical information with unprecedented spatial and spectroscopic resolution (< 1 nm and < 10 cm-1). We are interested in fundamental science and applications at the angstrom-scale, including charge transfer, electron localization and generation, photoabsorption, and photoemission. Our goal is to provide the capability to dynamically study chemical systems at the single-molecule level and visualize electronic and vibrational effects with sub-molecular resolution.

Probing chemistry of surface-supported nanostructure at the angstrom-scale

The design and fabrication of well-defined molecular nanostructures at solid surfaces is highly attractive for a variety of applications ranging from molecular optics and electronics to chemical sensors. To achieve this goal, we use molecular self-assembly, a powerful bottom-up approach for fabricating molecular nanostructures. The ordering of molecules on a substrate is governed by the interplay of intermolecular and interfacial interactions. We directly probe these nanocontacts using scanning tunneling microscopy (STM) and tip-enhanced Raman spectroscopy (TERS). With specifically chosen molecular units, the functionality of the overall nanostructure can be finely manipulated, which allows us to design and perfect atom- and energy-efficient fabrication of revolutionary new materials with tailored properties.

Determining the mechanism of chemical bond formation under various local environments

The catalysts and supports span a range of shapes and sizes. They feature a variety of surface defects and a great deal of crystallographic inhomogeneity. Catalysis involves chemical transformations that must be understood at the atomic scale since catalytic reactions present an intricate process of chemical bond-breaking and bond-forming steps on only a few isolated sites. The development of next-generation catalysts relies on defining and understanding the sites on the catalyst surface which are most responsible for their useful behavior. We aim to characterize active surface sites with single chemical bond sensitivity, which can correlate the local structure and function of catalysts.

Investigating interface of 2D materials and heterostructures at the atomic scale.

The study of quantum science involves diverse fields including physics, chemistry, and materials science. The discovery of new quantum materials and the understanding of quantum phenomena benefit from the improvements in experimental techniques. Therein, the combination of high spatial, energy, and chemical resolutions provided by state-of-the-art methods is highly desired to reveal unprecedented details of the quantum behaviors involving charge, spin, valley, lattice, and other degrees of freedom. We aim to achieve quantitative measurements of interfacial interaction at the angstrom scale and unveil many details regarding local interactions between these 2D monolayers. These will lay the groundwork for designing a new platform for realizing quantum devices.
