Webb1 jan. 2011 · In general, the Raman spectrum of nanocrystalline diamond consists of five bands, including one narrow peak at 1,333 cm −1 and four wide bands located around 1,150, 1,350, 1,450 and 1,570 cm −1. The first of these peaks is assigned to the diamond grains (the narrow line), all others to the amorphous carbon (grain boundaries) [ 11, 12 ]. Webb15 juli 2024 · Applicability of precise Raman spectral analysis of a-C:H films deposited using a plasma chemical vapor deposition (CVD) ... For the nanocrystalline diamond, additional sharp peaks appear near 1100 and 1300 cm −1 with peak intensities close to that at 1450 cm −1. WebbBy decreasing reacting gas pressure, nanocrystalline diamond films, the area of which reaches 2 inches were deposited with hot filament chemical vapor deposition (HFCVD) equipment.
