Field Emission of NoPo HiPCO Nanotubes
Emission of Electrons from Carbon Nanotubes was a project carried out by students of BMS College of Engineering, Electronics Engineering led by Sujay, Sanjana, Suhas and Shriram. The unique ability of Nanotubes to emit electrons was studied as part of this project. Carbon nanotubes (CNTs) are hollow cylinders of carbon atoms. Their appearance is that of rolled tubes of graphite, such that their walls are hexagonal carbon rings, and they are often formed in large bundles. The ends of CNTs are domed structures of six-membered rings, capped by a five-membered ring. There are two types of nanotubes: single-walled nanotubes (SWNTs)…
