Abstract

Using the methods of transmission electron diffraction, transmission electron microscopy, and electron paramagnetic resonance, we have analyzed the structure of thin carbon layers deposited on glass substrates, heated to a temperature of T ≈ 473 K, in a vacuum as a result of the exposure of a graphite target to a pulsed laser radiation of nanosecond duration and energy 2–8 J. It is shown that carbon films with an amorphous diamond structure undergo not only graphitization but also crystallization: polycrystalline diamond‐ and diamond‐graphite concretions are formed on their surface.
