Field Electron Emission from Electrophoretic Deposited MWCNT/ZnO Hybrid Film

Abstract:

Hybrid film of MWCNT/ZnO was prepared on the silver electrodes using electrophoresis deposition. A constant dc voltage of about 20V was applied to the electrodes and the MWCNT/ZnO was deposited on the surface of the anode electrode as a result. Field Emission Scanning Electron Microscopy was used to investigate the structure MWCNT/ZnO composite. The optical characterization was investigated by Raman Spectroscopy. The MWCNT film exhibits excellent field electron emission properties with high emission current densities, low threshold electric fields and good field emission stability.
