3D表面碳纳米管薄膜的生长及其强流脉冲发射的增强
Growth of CNT films on tridimensional surface and improvement on intense pulsed emission characteristics
摘要
Abstract
Three dimensional carbon nanotube films(3D-CNTs) were synthesized on micro-structure of tridimensional Si substrate with Ni layer by chemical vapor deposition(CVD). The CNT forest on the micro-structure surface are uniform, well aligned, and perpendicular to the substrate. In order to study the intense pulsed emission characteristics of CNTs cold cathode, the intense pulsed emission characteristics of CNTs cold cathode were measured repeatedly with a diode structure using a Marx generator as a voltage(under the same diode voltage discharge)source. Itis found that 3D-CNTs (grown on tridimensional substrate)cold cathode can offer not only higher emission peak current and current densities, but also better stability than planar-grown CNTs(P-CNTs)cold cathode.关键词
