Abstract :
Fabrication of pyrolitic carbon field emission cathodes is presented. Pyrolitic carbon is deposited on two types of substrates, polished glass and grinding substrates, through the process of low temperature vapor deposition. Deposition process times are 30, 60, and 180 minutes resulting to pyrolitic carbon thickness of 70, 150, and 500 nm, respectively. Current-voltage characteristics are measured and results show that better emission properties are observed in lesser thickness of pyrolitic carbon.
