摘要:
在传统的热阴极表面制备催化剂,通过自加热化学气相沉积法,成功地在热阴极表面生长出碳纳米管薄膜.碳纳米管薄膜具有较好的场致发射能力,通过二极结构下对该阴极的发射性能测试,得到了最大电流为5.5 mA的场致发射电流.该方法可以在不改变现有热阴极材料和器件结构的基础上,得到稳定的冷阴极发射电流,为热阴极向冷阴极过渡的研究提供了一种途径.
Abstract:
Based on a traditional thermal cathode,catalyst material layer has been deposited,and then carbon nanotube layer has been synthesized on the surface of the thermal cathode by self-heated chemical vapor deposition. As is known, carbon nanotube has excellent field emission properties,and the field emission capability of this cathode has been tested in a diode structure,a maximum 5. 4mA current has been obtained. We provide a new way to realize field emission large current on a traditional thermal cathode device while the cathode material and the whole structure need not be changed.
