J. Singh et al., LASER-ENHANCED SYNTHESIS AND PROCESSING OF DIAMOND FILMS FROM LIQUID HYDROCARBONS, Journal of applied physics, 73(9), 1993, pp. 4351-4356
We report synthesis of diamond films by pulsed laser irradiation on co
pper substrate immersed into liquid benzene. It is envisaged that carb
on released from benzene at the liquid-solid interface is converted in
to diamond as a result of rapid quenching from a high temperature. The
diamond crystallites were characterized using high resolution transmi
ssion electron microscopy imaging and electron diffraction techniques.
Growth of thicker diamond films by subsequent chemical vapor depositi
on has been investigated by transmission and scanning electron microsc
opy techniques. Thin diamond film deposited during liquid phase provid
ed seed for diamond growth during subsequent chemical vapor deposition
