High-frequency performance of scaled carbon nanotube array field-effect transistors
Mathias Steiner, Michael Engel, Yu-Ming Lin +10
We report the radio-frequency performance of carbon nanotube array transistors that have been realized through the aligned assembly of highly separated, semiconducting carbon nanot…
Wafer-scale Epitaxial Graphene Growth on the Si-face of Hexagonal SiC (0001) for High Frequency Transistors
Christos Dimitrakopoulos, Yu-Ming Lin, Alfred Grill +12
Up to two layers of epitaxial graphene have been grown on the Si-face of two-inch SiC wafers exhibiting room-temperature Hall mobilities up to 1800 cm^2/Vs, measured from ungated,…
Graphene field-effect-transistors with high on/off current ratio and large transport band gap at room temperature
Fengnian Xia, Damon B. Farmer, Yu-ming Lin +1
Graphene is considered to be a promising candidate for future nano-electronics due to its exceptional electronic properties. Unfortunately, the graphene field-effect-transistors (F…
Ultrafast graphene photodetector
Fengnian Xia, Thomas Mueller, Yu-ming Lin +2
The electronic properties of graphene are unique and are attracting increased attention to this novel 2-dimensional system. Its photonic properties are not less impressive. For exa…
Photocurrent imaging and efficient photon detection in a graphene transistor
Fengnian Xia, Thomas Mueller, Roksana Golizadeh-mojarad +5
We measure the channel potential of a graphene transistor using a scanning photocurrent imaging technique. We show that at a certain gate bias, the impact of the metal on the chann…
Utilization of a Buffered Dielectric to Achieve High Field-Effect Carrier Mobility in Graphene Transistors
Damon B. Farmer, Hsin-Ying Chiu, Yu-Ming Lin +3
We utilize an organic polymer buffer layer between graphene and conventional gate dielectrics in top-gated graphene transistors. Unlike other insulators, this dielectric stack does…
