The effect of atmospheric adsorbates, composed of dry oxygen (O 2 ) and ambient air, on electrical transport in high-quality and moderate-quality graphene samples was investigated. Atmospheric doping is seen to affect different samples at different r

We present a direct comparison between two fundamental methods of chemically doping the 2-dimensional graphene sheet: (1) passivation of dangling σ-bonds resulting from a vacancy defect and (2) charge transfer from adsorption on the pristine basal p

We present an experimental investigation of the impact of size effects on conductance in nanoribbons fabricated from epitaxial graphene. The material resistivity is seen to increase significantly (up to 13× for 50 nm wide ribbons) upon conversion fr

The localized surface plasmon resonance (LSPR) spectral band of a gold or silver nanoparticle is observed to shift as a result of the near-field plasmonic field of another nanoparticle. The dependence of the observed shift on the interparticle distan

Accurate threshold voltage (VT) modeling of bulk-MOSFETs is important for device optimization and circuit simulation. Existing VT models cannot model the impact of source/drain junction depth on VT rolloff. A new model is proposed that can accurately

This letter is the first to present a method to selectively hydrogenate the edges of sub-30-nm graphene nanoribbons (GNRs). After hydrogenation of the edges, the GNRs exhibit improved transport properties; carrier mobility increases by up to 50% at a

We present the first demonstration of p-type electrical transport in chemically doped epitaxial graphene (EG) nanoribbons produced on silicon carbide (SiC). The thermal annealing of cross-linked thin films of hydrogen silsesquioxane (HSQ) is found to

We analyze the system-level performance of graphene-based arithmetic logic units (ALUs) enabled by Klein tunneling. Although the proposed graphene device is idealized (many experimental hurdles remain), it is important nonetheless to assess graphene'
