Facile fabrication of suspended as-grown carbon nanotube devices
V. K. Sangwan, V. W. Ballarotto, M. S. Fuhrer +1
A simple scalable scheme is reported for fabricating suspended carbon nanotube field effect transistors (CNT-FETs) without exposing pristine as-grown carbon nanotubes to subsequent…
Charged impurity scattering in bilayer graphene
Shudong Xiao, Jian-Hao Chen, Shaffique Adam +2
We have examined the impact of charged impurity scattering on charge carrier transport in bilayer graphene (BLG) by deposition of potassium in ultra-high vacuum at low temperature.…
Frequency-dependent complex conductivity of an organic thin-film transistor
Daniel R. Lenski, Adrian Southard, Michael S. Fuhrer
We measure the complex impedance between source/drain electrodes and the gate electrode of a pentacene thin-film transistor (TFT) at frequencies 50 Hz < omega/2pi < 20 kHz. Modelin…
Massless and massive particle-in-a-box states in single-and bi-layer graphene
Sungjae Cho, Michael S. Fuhrer
Electron transport through short, phase-coherent metal-graphene-metal devices occurs via resonant transmission through particle-in-a-box-like states defined by the atomically-sharp…
