These ''carbyne'' crystals were surrounded by disordered diamond crystals

( Figure 5.2(a) ) . The film thickness was determined from SEM observation,

and was about 15 m m. EDX analysis shows that the deposited films were
constituted of pure carbon (Figure 5.2(b)).

5.3.1.2 Carbon Film Deposited at s ¼ 1.1

Crystals with a hexagonal form assigned to ''carbyne'' or ''tetragonal''
crystallized diamond were observed (Figure 5.3(a)). The film's texture was
constituted of small crystals. The average crystal size is about 1-2 m m. These
crystals were surrounded by diamond crystals. The film thickness was about
10 m m. EDX analysis shows that the deposited films were constituted of pure
carbon (Figure 5.3(b)).
