In this study, carbon nanotubes (CNTs) were synthesized on a catalyst of zinc oxide (ZnO) nanorods prepared with a hydrothermal process. The surface morphology of the CNTs was studied with scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and the structural properties and chemical compositions of the CNTs were studied with Raman spectroscopy and energy dispersive spectrometer...
DLC and metal/DLC nanocomposites coatings deposited by means of pulsed laser deposition /PLD/ technique, using high power UV nitrogen laser are described. The DLC and M/DLC nanocomposite coatings are deposited on substrates stents made from 316L SS material and NITINOL (NiTi) alloy. The tests and analysis of the morphology-, structure-, physical-, mechanical- electrochemical- and chemical parameters...
In this paper, multi-walled carbon nanotube (MWCNT) ink was selectively patterned by inkjet printing on substrates to form conductive traces and electrodes for interconnection application. MWCNT was firstly functionalized using concentrated acid and dispersed in deionized water to form a colloidal solution. Various concentrations of MWCNT were formulated to test the stability of the solution. The...
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...
In this paper an experimental approach of depositing diamond like carbon (DLC) on metal substrates has been described. By electrolysis of 10% (by mass) camphoric solution in methanol, attempts were made to deposit DLC films on Copper (Cu) and Aluminum (Al) substrates at room temperature. Solution is prepared using camphor (C10H16O), a natural source in methanol solvent. At first we applied this approach...
The electron field emission characteristics from multiwalled carbon nanotube (MWNT) films grown on two different substrate materials have been studied in this paper. The MWNT films were grown on a flat conductor surface (stainless steel) and a flat insulator surface (quartz). The field emission experiments were carried out under a diode configuration. It was found that the film on the quartz surface...
