We report the realization of top-gated graphene nanoribbon field effect transistors (GNRFETs) of ∼10 nm width on large-area epitaxial graphene exhibiting the opening of a band gap of ∼0.14 eV. Contrary to prior observations of disordered transpor

We present a study of the noise properties of single-layer exfoliated graphene as a function of gate bias. A tunnel/trap model is presented based on the interaction of graphene electrons with the underlying substrate. The model incorpo- rates trap po

One-dimensional nanostructures of graphene such as graphene nanoribbons (GNRs) can prove attractive for digital electronics in the form of interband tunneling transistors, as they are capable of high drive currents. Here, we report on the transport p

Transient absorption microscopy was employed to image charge carrier dynamics in epitaxial multilayer graphene. The carrier cooling exhibited a biexponential decay that showed a significant dependence on carrier density. The fast and slow relaxation

Spurred by the knowledge of isolation of graphene, other 2D transition-metal dichalcogenide materials in the form of MX 2 (where M=transition metal such as Mo, W, Ti, Nb, etc. and X=S, Se, or Te) have drawn considerable attention. The MX 2 family mat

Terahertz technology promises myriad applications including imaging, spectroscopy and communications. However, one major bottleneck at present for advancing this field is the lack of efficient devices to manipulate the terahertz electromagnetic waves

We investigate high-field transport in graphene nanoribbons (GNRs) on SiO2, up to breakdown. The maximum current density is limited by self-heating, but can reach >3 mA/um for GNRs ~15 nm wide. Comparison with larger, micron-sized graphene devices re

Graphene is being investigated as a promising candidate for electronic devices. For digital electronic devices, a substantial bandgap is necessary. It is possible to open a bandgap in graphene by quantum confinement of the carriers in patterned graph
