Abstract:
Nanopatterned graphene constitutes a new class of graphene-based nanostructures (GBNs), ranging from zero-dimensional (0D) nanodots, 1D nanoribbons to 2D nanohole superlattices. They exhibit many interesting electronic and transport properties showing great promise to open a new paradigm for future nanoelectronics and spintronics. In this talk, I will discuss our recent studies in using GBNs as building blocks to design novel electronic/spintronic materials and device architectures. These include “electron beam manipulators”, “quantum cellular automata”, and “spin semiconductors” with fully spin-polarized carriers. In addition, I will address briefly the issue of graphene edge stability presenting interesting quantum manifestations of graphene edge stress and warping instability.
