PROJECT DESCRIPTION

Gas Sensing and Charge Transport Mechanisms in Multiwalled Carbon NanoTubes

Highly ordered porous alumina templates were fabricated by a two-step Anodization process of high purity aluminum tape in a 0.3M Oxalic acid medium. Multi walled carbon nanotubes (MWCNT) were grown in these templates using Chemical vapor deposition (CVD) by Xylene pyrolysis at 700^oC without the use of a catalyst. Post growth characterization by Scanning Electron Microscopy revealed that the nanotubes were aligned, open ended on both sides and walls were crystalline.
