分散定向碳纳米管阵列的制备及场发射性能
Preparation and field emission properties of aligned carbon nanotube arrays with low density
摘要
Abstract
Using pulse electrochemical deposition methods, the low density nano-particles with diameter about 150 nm of Ni were deposited on silicon wafer coated by Cr in NiSO4 plating solution. Aligned carbon nanotubes were synthesized by plasma enhancement chemical vapor deposition from the gas containing acetylene and ammonia. Pre-etching affection of plasma was also studied. Field emission property was measured for the low density carbon nanotubes arrays, the turn-on electric field strength is about 2.39 V/(m, which shows that the aligned carbon nanotubes with low density can be decreased the screen effect, and enhances the field emission property.关键词
