Comparison of electron emission properties of silicon coated carbon nanotubes in O2 atmosphere

We studied the electron emission of silicon coated CNT with various O
₂
partial pressure. The electron emission currrent shows differen reduction rate with growth condition and gas pressure. However, a degradation rate of electron emission current of silicon coated CNTs show deareases compared with conventional CNTs. Enhanced life time with reduced degradation rate with silicon coated CNTs appear to silicon protection layer on CNTs.
