Deposition of diamond thin films on non-diamond substrates at low pres
sures (< 760 torr) and low temperatures (< 2000 degrees C) by chemical
vapour deposition (CVD) has been: the subject of intense research in
the last few years. The structural and the electrical properties of CV
D diamond films grown on p-type < 111 > and high-resistivity (> 100 k
Ohm-cm) < 100 > oriented silicon substrates by hot filament chemical v
apour deposition technique are described in this review paper.
