Field Electrons Emission Properties of Low-Dimensional Carbon-Based Nano-Materials

利用等离子辅助化学气相沉积技术制备了一系列低维碳基纳米材料,如碳纳米管、碳纳米管锥及金刚石纳米锥等,由于其优异的力学、热学及电学特性,而成为真空场致电子发射的优选材料。本文介绍在单根和阵列结构低维碳基纳米材料的场电子发射特性及发射机制上的研究进展,并探讨这一领域今后的发展趋势。

A series of carbon-based nano-materials,like carbon nanotube,carbon nanocone and diamond nanocone,can be fabricated by using plasma-enhanced CVD technology,and they can be employed as promising candidates for vacuum field electrons emission due to their outstanding mechanical,thermal and electronic properties.In this paper,recent progresses are reported on the field electrons emission properties and mechanisms for individual and array carbon-based low-dimensional materials,and the future research trends in this field are discussed.
