Delay Analysis of Graphene Field-Effect Transistors
Han Wang, Allen Hsu, Dong Seup Lee +3
In this letter, we analyze the carrier transit delay in graphene field-effect transistors (GFETs). GFETs are fabricated at the wafer-scale on sapphire substrate. For a device with…
BN/Graphene/BN Transistors for RF Applications
Han Wang, Thiti Taychatanapat, Allen Hsu +4
In this letter, we demonstrate the first BN/Graphene/BN field effect transistor for RF applications. The BN/Graphene/BN structure can preserve the high mobility of graphene, even w…
Nonlinear THz Conductivity Dynamics in CVD-Grown Graphene
Harold Y. Hwang, Nathaniel C. Brandt, Hootan Farhat +3
We report strong THz-induced transparency in CVD-grown graphene where 92%-96% of the peak-field is transmitted compared to 74% at lower field strength. Time-resolved THz-pump/THz-p…
