Sharp Switching by Field-Effect Bandgap Modulation in All-Graphene Side-Gate Transistors
IEEE Journal of the Electron Devices Society, 2015 Graphene is a 2-D electronic material that has drawn intensive interest due to its high carrier mobility, film flexibility, and tunable bandgap. The unique bandgap modulation by the transverse electrical field in the graphene nanoribbon (GNR) offers new ...

Electronic Structure of Fullerene Nanoribbons. [PDF]
ACS NanoUsing first-principles calculations, we examine the electronic structure of quasi-one-dimensional fullerene nanoribbons derived from two-dimensional fullerene networks. Depending on the edge geometry and width, these nanoribbons exhibit a rich variety of properties beyond conventional quantum confinement, including direct and indirect band gaps ...

Making Graphene Nanoribbons Photoluminescent [PDF]
Nano Letters, 2017 We demonstrate the alignment-preserving transfer of parallel graphene nanoribbons (GNRs) onto insulating substrates. The photophysics of such samples is characterized by polarized Raman and photoluminescence (PL) spectroscopies. The Raman scattered light and the PL are polarized along the GNR axis.

EPL (Europhysics Letters), 2014 Edge-induced gap states in finite phosphorene layers are examined using analytical models and density functional theory. The nature of such gap states depends on the direction of the cut. Armchair nanoribbons are insulating, whereas nanoribbons cut in the perpendicular direction (with zigzag and cliff-type edges) are metallic, unless they undergo a ...
