Abstract :
In this work, we have formed diamond cone arrays by plasma etching of diamond film without masking. Diamond film was grown on Si (100) substrate by hot-filament chemical vapor deposition (HFCVD) method using the mixture of CH4 and H2. Scanning electrons microscopy (SEM) was used to study the morphology of as-formed diamond cone arrays. Micro Raman spectroscopy was used to characterize the phase purity of the diamond film before and after etching. Field emission properties of diamond films with different cone densities were also studied.
