Two-Dimensional Materials & Heterostructures

Two-dimensional nanostructures have been emerging recently as new quantum confined materials with unique structure and size dependent properties. Our research is geared towards the development of new 2D materials via “soft chemistry“ and their use as functional nanoscale building blocks to construct judiciously designed hybrid superlattices with tailor-made electronic, optical and magnetic properties. By joining the synthetic tools of nanochemistry, colloidal chemistry, and solid-state chemistry we envision the rational design of metastable, unconventional and multifunctional solids with precisely tuned structures, composition, and functionality.
