Abstract:
A method of fabricating a thin film transistor, the method includes applying a first ink containing metallic particles to a first screen mask, and using the first screen mask to deposit the first ink to form a source electrode and a drain electrode on a substrate bearing a layer of carbon nanotubes (CNT). The method includes applying a second ink containing a dielectric material to a second screen mask, and using the second screen mask to deposit the second ink to form a layer of the dielectric material on the layer of CNT between the source electrode and the drain electrode. The method includes applying a third ink containing metallic particles to a third screen mask, and using the third screen mask to deposit the first ink to form a metallic gate electrode on the layer of the dielectric material to form the thin film transistor.
Abstract:
Hybrid silicon-carbon nanostructured electrodes are fabricated by forming a suspension including carbon nanostructures and a fluid, disposing the suspension on a substrate, removing at least some of the fluid from the suspension to form a carbon nanostructure layer on the substrate, and sputtering a layer of silicon over the carbon nanostructure layer to form the hybrid silicon-carbon nanostructured electrode. Sputtering the layer of silicon facilitates fabrication of large dimension electrodes at room temperature. The hybrid silicon-carbon nanostructured electrode may be used as an anode in a rechargeable battery, such as a lithium ion battery.
Abstract:
Nanowires are formed in a process including fluidized bed catalytic vapor deposition. The process may include contacting a gas-phase precursor including a metal or a semiconductor with a catalyst in a reaction chamber under conditions suitable for growth of nanowires including the metal or the semiconductor. The reaction chamber includes a support. The support can be, for example, a particulate support or a product vessel in the fluidized bed reactor. Nanowires are formed on the support in response to interaction between the gas-phase precursor and the catalyst. The nanowire-laden support is removed from the reaction chamber, and the nanowires are separated from the support. An anode or a lithium-ion battery may include nanowires formed in a fluidized bed reactor.
Abstract:
An asymmetric electrochemical capacitor including an anode, a cathode, and an electrolyte between the anode and the cathode. The anode includes manganese dioxide (MnO 2 ) nanowires and single-walled carbon nanotubes. The cathode includes indium oxide (In 2 O 3 ) nanowires and single-walled carbon nanotubes. The asymmetrical electrochemical capacitor can be fabricated by forming a first film including manganese dioxide nanowires and single-walled carbon nanotubes, forming a second film including indium oxide nanowires and single-walled carbon nanotubes, and providing an electrolyte between the first film and the second film such that the electrolyte is in contact with the first film and the second film.
