外文摘要：CNx/C nanotube arrays were fabricated via a simple chemical modification porous alumina membrane in situ method. The nanotubes consist of two sections featuring straight and hollow cylinder structure, one sectionmade of N-doped carbon and the other one made of pure carbon. The metal-semiconductor junction was formed in the middle as a result of being doped or undoped with nitrogen. The onoff current ratio at +/- 5 V is 25. The applicability of chemical modification in situ technique provides us with a good opportunity for practical use of the multiwall nanotube for future nano-devices.
