Contact resistance between a carbon nanotube and a metal is governed by the structure of the contact. In order to investigate an effect of the contact structure between a multi-walled carbon nanotube (MWNT) and the metal on electric properties, we studied the structural change of the contact region during the passage of a current by in-situ transmission electron microscopy with the simultaneous current...
Multifunctional hybrid nanostructures composed of noble metais, semiconductors, metal oxides, and carbonaceous moieties are fabricated based on block copolymer self-assembly coupled with sol-gel process and galvanic displacement reaction. A new protocol for the build-up of multilayers of inorganic nanoparticles constructed by stepwise build-up of amphiphilic micellar nanotemplates is established....
One dimensional (1D) Schottky diodes between metals and carbon nanotubes (CNTs) can separate the photo-generated electron-hole (e-h) pairs in order to produce photocurrent in the CNT infrared (IR) sensors for detection and quantification. However, the traditional Schottky barrier theories developed for the metal and planar semiconductor contacts are different from the contacts between metal and CNT...
A resistive sensing device based on functionalized multi-walled carbon nanotubes (f-MWNTs) utilizing chemical oxidation method was fabricated successfully and proved sensitive to ethanol vapor. Dielectrophoresis (DEP) manipulation was used to achieve CNTs alignment between pairs of gold microelectrodes in fabricating the CNT sensing elements. I-V characteristics were tested to ensure that the sensors...
As IC performance increases, many technical challenges appear in the areas of current-carrying capacities, thermal management, I/O density, and thermal-mechanical reliability. To address these problems, the use of aligned carbon nanotubes (CNTs) has been proposed in IC packaging for electrical interconnect and thermal interface materials (TIMs). The theoretically superior electrical, thermal, and...
