碳纳米管场发射电流饱和特点Carbon Nanotube Field-Emission Current Saturation



Since the first report of CNT (Carbon Nanotube) field emission in 1995 [1], CNT has shown the most application potential and research value as field emission source because of its unique structure, outstanding electrical properties, nano-scale and great aspect ratio. Meanwhile, the CNT field-emission current shows self-saturation feature under high electric field, which is a promising advantage for energy saving of FED (Field Emission Display) technology. This paper introduced five mechanisms responsible for CNT field-emission current saturation including field desorption, contacting resistance, space charge effect, neighboring nanotube interaction and non-metallic local states, which are very important for the analysis and improvement of CNT FE devices.
