Contact resistance and shot noise in graphene transistors

Graphene’s distinctive band structure gives rise to exciting new transport properties and promising applications for carbon-based electronics.1–3 When measuring the conductance or current noise in a nanotube or a sheet of graphene, the properties of the contacts can matter as much as the electronic structure of the nanotube or graphene itself. In semiconducting nanotubes or graphene nanoribbons...

Contact Resistance and Channel Conductance of Graphene Field-Effect Transistors under Low-Energy Electron Irradiation

We studied the effects of low-energy electron beam irradiation up to 10 keV on graphene-based field effect transistors. We fabricated metallic bilayer electrodes to contact mono- and bi-layer graphene flakes on SiO₂, obtaining specific contact resistivity ρ c ≈ 19 k Ω · µ m 2 and carrier mobility as high as 4000 cm²·V-1·s-1. By using a highly doped p-Si/SiO₂ substrate as the back gate, we analy...

High-Electron Mobility Graphene Channel Transistors for Millimeter-Wave Applications

We have fabricated and characterized the graphenechannel field effect transistors (GFETs) on semi-insulating SiC substrates. In our first GFETs, the device exhibits n-type FET operation with the transconductance of 0.1 mS/mm at the drain voltage of 0.5 V. The current gain cutoff frequency characterized by S parameter measurement is 0.5 GHz. These characteristics are primarily limited by the low...
