Latest Research Highlights

We find a new way to active basal plane of molybdenum disulfide to catalyze hydrogen evolution reaction by creating sulfur vacancies. We further optimize the catalyst by applying tensile strain to this atomically thin catalyst. This work demonstrated that vacancy and strain engineering could be power tools to create active catalysts for various reactions beyond hydrogen evolution.

This is the first realization of textured local strain in monolayer molybdenum disulfide. With spatially distribution of local strain gradient, we created an "artificial crystal" that has a broader absorption spectrum. The said artificial crystal behaves as an array of exciton funnels that may serve as a platform for fundamental research and prototype of new optoelectronic device.
