Abstract Scanning electron microscopy and Raman shifts were used to study the process of diamond nucleation and growth using C60 in the hot filament chemical vapour deposition (HFCVD) system. The process of nucleation and growth of diamond films on silicon wafer using C60 as intermediate layer in HFCVD system is described. In order to increase the density of diamond nuclei on the wafers, it is not necessary to use negative bias. The UV-light pre-treatment is not beneficial for improving the diamond nucleation. The multi-layers of C60 molecules, but not a monolayer, can increase the density of diamond nuclei in the presence of H atoms.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
