The research interest of our team focuses on the understanding and eventual control of the chemical and physical processes occurring at the atomic to the macroscopic scale, for creating novel functional materials and devices. Our prime experimental tool is the low-temperature scanning probe microscope, namely scanning tunneling microscope (STM) and non-contact atomic force microscopy (nc-AFM). These scanning probe techniques offer the unique capability of exploring the local electronic and magnetic properties of individual atomic and molecular nanostructures at surfaces.

 

LT-SPM Study of Nanomaterials and Devices

Our team is also interested in the bottom-up growth of various novel low-dimensional carbon nanostructures such as zero-dimensional graphene quantum dots (GQDs), one-dimensional graphene nanoribbons (GRNs) and two-dimensional carbon frameworks (2D-COFs) on surfaces. We also aim to explore the electronic, optical and magnetic properties of these carbon nanostructures and make useful devices out of these low-dimensional carbon nanostructures.

 

Investigating Chemical Reaction Dynamics

We aim to understand the microscopic mechanisms of surface-catalyzed chemical reactions and provide atomic insights into industrial related chemical processes.

 

Engineering Organic Superlattice

Our research team also targets to tailor the electronic and magnetic properties of 2D materials through creating novel organic superlattices on their surfaces for optimizing their device performance.

 

Atomic-scale Growth Dynamics of 2D Materials

The synthesis of large-scale highly crystalline 2D materials is one of the most challenging issues faced by the scientific community. Our group aims to address this critical issue by researching on the growth dynamics at the atomic domain using HT-SPMs.

 

Probing Atomic-scale Chemistry and Physics in a Device Environment

We are interested in exploring atomic-scale chemistry and physics of individual atomic and molecular nanostructures on various surfaces, in particular on insulating substrates and gated 2D materials devices. Such investigations may open up new research avenues in the field of single-atom and single-molecule based electronic devices.
