About Me

I was born in a small village where everybody knows everybody. The peaceful country life brought me a lot of beautiful memories. I became quite interested in nature during my childhood. When I was a student, my favorite subjects were physics and chemistry and my deep enjoyment then was playing equations, formula and doing calculation and studying science. I feel fortunate that I can work on what I love – teaching chemistry and doing scientific research at Ball State.

My College Experience

I received my Ph.D. from RWTH Aachen University (Germany) in Prof. Thomas Wandlowski group. Then I worked as a postdoc at Arizona State University, and then at Temple University in Prof. Borguet lab before I joined Ball State University. My research belongs to analytical, materials, and physical chemistry, with a focus on the electrochemical scanning tunneling microscopy and its applications in molecular assembly and devices, nanomaterials, energy conversion.

What I have Learned

During my life journey and career path, I came a long way and learned a lot, often by lessons. The most important thing I learned is never giving up. Once you know your dream and your love, pursuing it with your whole heart.  Second, be prepared. The opportunity is only waiting for the people who are well-prepared. Third, be interested and curious.  Interest is the best teacher (Albert Einstein), especially true for science.

Research Interests

Li Research Group

Nano-materials and devices (photovoltaic or solar cells), electrochemistry, electrochemical scanning probe microscopy (STM) and its applications in energy conversion, atomic force microscopy (AFM) lithography, molecular assembly and single-molecule electrical properties.

Preparation of semiconductor nanomaterials and applications in energy conversion

Semiconductors have demonstrated great capacity for applications in energy storage devices, solar light conversion, and water-splitting. Semiconductors utilized in these applications must hold appropriate physio-chemical properties including suitable band gap, proper mechanical and electrochemical resistance, and relatively stable excitation state among others. Promoting the desired properties could be achieved by structural doping of the materials with certain elements, substitution of rare and costly elements with less expensive ones, application of novel methods for tuning particle distribution, etc. In this project, a variety of semiconductor nanomaterials will be prepared and these materials will be applied to photovoltaic cells, energy storage, water splitting, and environmental remediation.

EC-STM study of the adsorption and molecular assembly of organic molecules at electrode-electrolyte interfaces

Adsorption and self-assembly of organic molecules on metal surfaces or at the metal-electrolyte interfaces is a fundamentally important topic because the study of the interactions between adsorbates (molecules) and metal substrates can provide valuable information to other chemical reactions and processes such as surface corrosion, asymmetric heterogeneous catalysis, electrochemical sensors, degradation of organic pollutants, surface-catalyzed reactions, and charge transfer in molecular devices. Self-assembly of molecules on substrates also provides a unique route to create supramolecular nanostructures. We have systematically studied the adsorption and assembly of a series of aromatic carboxylic acid on Au(111) surface to discover the key parameters that influence molecular patterns, surface coverage, unit cells.
