Highly Transmissive Carbon Nanotube Forests Grown at Low Substrate Temperature

Spinnable carbon nanotube forests grown on thin, flexible metallic substrates

Towards the goal of providing a continuous process for the solid-state fabrication of carbon nanotube sheets and yarns from carbon nanotube forests, we report the growth of yarnspinnable and sheet-drawable carbon nanotube forests on highly flexible stainless steel sheets, instead of the conventionally used silicon wafers. Sheets and yarns were fabricated from the 16 cm maximum demonstrated fore...

Highly aligned carbon nanotube forests coated by superconducting NbC.

The formation of carbon nanotube and superconductor composites makes it possible to produce new and/or improved functionalities that the individual material does not possess. Here we show that coating carbon nanotube forests with superconducting niobium carbide (NbC) does not destroy the microstructure of the nanotubes. NbC also shows much improved superconducting properties such as a higher ir...

Low temperature conductivity of carbon nanotube aggregates.

We compare, over wide temperature ranges, the transport properties of single-wall carbon nanotubes arranged in the form of aligned arrays or in the form of fibres. The experimental data show that both the forms of aggregates present a crossover in the transport mechanism from three-dimensional hopping of the electrons between localized states at high temperature to fluctuation-induced tunnellin...

Highly Reliable Low Temperature Ultrathin Oxides Grown Using N2O Plasma

In this paper, the N2O plasma oxides in-situ grown on CF4 plasma pretreated silicon substrate is proposed and demonstrated having excellent characteristics. Those are precise thickness control, low temperature fabrication, low leakage current, and high reliability. Those good features will enhance the scaling down ability of CMOS devices. The mechanisms that make the process success are also di...
