Paper Abstract

Carbon nanotubes (CNT) were synthesized using a DC thermal plasma method. Nanotubes from the cathode were analyzed by electron microscopy and were then studied for their field emission properties. The CNTs were deposited on a tungsten wire, which acted as the cathode. The main aim was to push the distance between the electrodes outside those previously attempted. The field emission current was measured using a phosphorous coated ITO (indium tin oxide) glass plate. Images of the field emitted electrons impinging on the phosphorous screen were also recorded and analyzed. The I-V curves for the field emission were recorded at various distances between the electrodes. Similar studies were performed for commercially obtained (from two different sources) single-walled carbon nanotubes and the results compared with the as-produced nanotubes.
