Research Vision
Challenge: The large-scale production and processing of pristine 2D nanosheets while exerting control over their unique properties.
My Approach: Advancing solution-processable methods to induce exceptional properties in conventional materials as well as designing and developing novel materials amenable to solution-processable techniques.
Past Experience
A novel route for high performance transition metal dichalcogenide (TMD) nanosheets from bulk powder. With internal quantum efficiencies (IQE) up to 90%, devices achieved benchmark performances for solar-to-chemical energy conversion by solution-processed nanosheets.
A scalable method for bandgap engineering 2D TMDs via atomic alloying. With control over chemical makeup and composition, this is a seminal demonstration of a solution-processable route for alloying nanosheets and controlling their resulting optoelectronic properties.
A roll-to-roll apparatus for the continuous deposition of thin films of semiconducting nanosheets for optoelectronic applications (e.g. solar-to-chemical energy conversion). In addition to films on the m^2 scale, device engineering can take place via multiple depositions to control thickness and/or heterojunction formation.
