This paper presented a novel sacrificial electrode dielectrophoresis method which was able to fabricate a large amount of totally discrete SWNT devices on a single chip synchronously. The discrete devices included a pair of W/Au opposed electrodes and SWNT bundles that were assembled between electrodes by DEP. We used Al lines to connect the two electrodes of all devices to two large Al pads. AC DEP...
In this paper we investigate the properties of SWCNTs film-silicon vertical heterojunction fabricated by simple drop-casting method. The vertical heterojunction shows a good rectifying characteristic, which demonstrates a good Schottky contact, with a Schottky barrier height of 0.46eV. At high temperature, thermionic emission is the dominant transport mechanism, while tunneling begins to lead below...
This paper presents the design, fabrication and synthesis of a carbon nanotube Pirani vacuum gauge which comprises 5-μm-long SWNTs as heater and Au/W as electrodes. Results show that the TCR of SWNTs is negative and about -0.004/°C. SWNTs Pirani vacuum gauge was demonstrated with a dynamic range of 2500Pa to 40Pa in air environment. The average sensitivity of SWNTs Pirani vacuum gauge is about 914Ω/Pa...
