Abstract:
Hydrogenated nanodiamond films consisting of 300 and 10–30nm grain sizes were examined by high resolution electron energy loss spectroscopy. C–H stretching modes were identified at 350, 360, and 375meV. The mode at 375meV was enhanced in the case of 10–30nm grain size and it is stable up to in situ annealing to & gt;800°C. Complete hydrogen desorption occurs upon annealing to 1000°C. Exposure of the nanodiamond film to atomic hydrogen results in a strong quenching of the 375meV C–H mode, most likely due to preferential etching of (sp2)-carbon-hydrogen at the surface and grain boundaries of the films.
