摘要：
Diamond thin films have been synthesized by hot-filament chemical vapor deposition process using a mixture of methane and hydrogen gases. The samples were subjected to very high-energy ion irradiation (100 MeV Au7+ ions). The field emission characteristics of ion-irradiated samples have been studied. High emission currents and low turn-on and threshold fields were obtained for ion-irradiated samples. The as-deposited and the ion-irradiated samples have been characterized by X-ray Diffraction, Scanning Electron Microscopy and Micro-Raman Spectroscopy techniques and the resulting changes are correlated with field emission results.
