FABRICATION AND FIELD-EMISSION PROPERTIES OF POLY-DIAMOND FILMS

By using a substrate transferring technique, poly-diamond thick films having a smooth or rough surface could be fabricated as field emitter materials. The diamond film with a smooth surface, which was transferr ed from the interface between the (100) Si substrate and poly diamond deposited by plasma-enhanced CVD, showed better field emission propert ies in terms of emission current density with improved vacuum level de pendence as compared with original poly-diamond film from a rough surf ace.
