Molecular motions and chemical reactions occurring in constrained space play key roles in many catalysis and energy storage applications. However, its understanding has been impeded by difficulty in detection and lack of reliable model systems. In this work, we report geometric and chemical manipulation of O2 diffusion and ensuing O2-mediated charge transfer (CT) that occur in the 2D space between single-layer transition metal dichalcogenides (TMDs) and dielectric substrates. As a sensitive…

Two-dimensional materials represented by graphene and transition metal dichalcogenides undergo charge transfer (CT) processes and become hole-doped in strong mineral acids. Nonetheless, their

Optical Imaging of Redox and Molecular Diffusion in 2D van der Waals Space.

In this Account, breakthroughs in unraveling the chemical origin and mechanistic requirements of the hidden CT reactions using 2-D crystals are reviewed and the complete mechanism of the fundamental charge exchange summarized in this Account will be essential to exploring material and device properties of other low-dimensional materials.



On the wetting translucency of hexagonal boron nitride.

Molecular dynamics simulations of water droplets and water films on hBN layers supported on a gold-like hydrophilic substrate confirm a distinct wetting translucency nature of hBN very similar to that observed in graphene.

Redox-governed charge doping dictated by interfacial diffusion in two-dimensional materials

It is reported that ambient redox reactions govern charge transfer doping in graphene and tungsten disulfide and sets an ambient limit to material properties, which is universal to not only 2D but also other forms of materials.
