Abstract:
Researchers at the Plasma Physics Research Center of Iran's Islamic Azad University devised a new method to improve the synthesis and growth of carbon nanotubes.

New Method Presented for Synthesis, Growth of Carbon Nanotubes

Iran | Posted on December 29th, 2009

The new method has revealed a way to produce the nanotubes that have applications in manufacturing electron emitters and solid devices with high thermal conductivity.

Since 1991, along with the discovery of carbon nanotubes, researchers have always attempted to optimize their production and to utilize them in different industries.

Majid Mojtahedzadeh Larijani, one of the researchers, undertook this study with the aim of "Introducing a novel method for carbon nanotubes' growth specially on the beds with catalytic base by means of ionic bombardment".

"The bed used in this study was steel. First in the process, sub-layer underwent surface treatment by argon ionic bombardment of the surface at different ion energies and doses. Then, carbon nanotube growth on bombarded samples using hydrogen and steel gases was accomplished by TCVD method and finally samples were analyzed by TEM, SEM, AFM, and Raman spectroscopy devices," Mojtahedzadeh said in an interview with Iran Nanotechnology Initiative Council, elaborating on the project.

The results showed that ion energy and dose in which sub-layer surface turns into fine grains are very appropriate for the growth of dense and adhesive carbon nanotubes.

"These nanotubes could be applied for manufacturing electron emitters and solid devices with high thermal conductivity in electronics industry," he added.
