A chemical route to graphene for device applications.
Electric conductivity measurements indicate a 10000-fold increase in conductivity after chemical reduction to graphene, and temperature-dependent conductivity indicates that the graphene-like sheets exhibit semiconducting behavior.
Detection of NO2 down to ppb levels using individual and multiple In2O3 nanowire devices
We demonstrate detection of NO2 down to ppb levels using transistors based on both single and multiple In2O3 nanowires operating at room temperature. This represents orders-of-magnitude improvement
In2O3 nanowires as chemical sensors
We present an approach to use individual In2O3 nanowire transistors as chemical sensors working at room temperature. Upon exposure to a small amount of NO2 or NH3, the nanowire transistors showed a
Template-free directional growth of single-walled carbon nanotubes on a- and r-plane sapphire.
High-throughput growth of highly aligned single-walled carbon nanotubes arrays on a-plane and r-plane sapphire substrates using chemical vapor deposition with ferritin as the catalyst may enable the construction of integrable and scalable nanotube devices and systems.
Multilevel memory based on molecular devices
Multilevel molecular memory devices were proposed and demonstrated for nonvolatile data storage up to three bits (eight levels) per cell, in contrast to the standard one-bit-per-cell (two levels)
Band engineering of carbon nanotube field-effect transistors via selected area chemical gating
This letter presents an approach to engineer the band structure of carbon nanotube field-effect transistors via selected area chemical gating. By exposing the center part, or the contacts, of
Magnetite (Fe3O4) Core−Shell Nanowires: Synthesis and Magnetoresistance
High quality MgO/Fe3O4 core−shell nanowires have been successfully synthesized by depositing an epitaxial shell of Fe3O4 onto single crystal MgO nanowires. The material composition and stoichoimetric
Single crystalline magnetite nanotubes.
The synthetic strategy presented here may be extended to a variety of materials such as YBCO, PZT, and LCMO which should provide ideal candidates for fundamental studies of superconductivity, piezoelectricity, and ferromagnetism in nanoscale structures.
