[Abstract]

Since the discovery of quantum confinement effects, the emerging classes of two-dimensional (2D) materials have been widely explored to provide desirable electronic and optical properties. It is only recently, though, that advances in synthesis and fabrication techniques have enabled suitable control over their nanostructure interfaces to make efficient devices. Utilizing multi-scale simulations, we explored the potential of interfacial design by probing a variety of transition and transport phenomena, including light absorption, charge transfer, charge/phonon transport, atom diffusion etc, at 2D heterostructures with different functionalities and architectures. In this talk, prototype systems belong to the categories of in-plane, stacking, and hybrid 2D heterostructures will be discussed to illustrate the ideas. Specifically, I will show the possibility of manipulating charge dynamics and phonon transport, a new perspective to understand the transparency of 2D material, and a flexible means to optimize catalytic properties, via the rational design of nanoscale interface array.
