Abstract
Fifty to hundred nanometers carbon nanotube and zinc oxide (CNT–ZnO) nanocomposite were successfully synthesized with two different methods. We have initially prepared multi-walled carbon nanotubes (MWCNTs) by the plasma enhanced chemical vapour deposition method. By two different methods, then, ZnO layers were coated on the tubes. Radio frequency sputtering was one of the ways to directly deposit ZnO thin layer on the MWCNTs. Alternatively, we used thermally physical vapour deposition for making thin Zn film to oxidize it later. Scanning electron microscopy and also Raman spectroscopy measurements of the prepared samples confirmed the presence of ZnO nanolayers on the CNT bodies. By field emission (FE) measurements we found that ZnO deposited CNTs have a more efficient emissivity than that of CNTs alone. FE behavior of CNTs was improved by ZnO coating on the tubes. These changes were more sensible by oxidation technique than by sputtering of ZnO. Uniformly coated ZnO layers on CNTs would not significantly changes the FE properties. But, bead-shaped ZnO coated on tubes by the oxidation manner, were scattered on the tubes and behave as a good emitter source.
