A new hybrid CVD-powder flowing technique has been adopted in order to grow diamond-based composite materials in form of thin films, coatings and free-standing layers. We report details of the synthesis procedure that allows to control incorporation of nanometer-sized powdered species (metals and semiconductors) in form of aggregates, clusters or nanosized dispersions inside a polycrystalline diamond matrix. The focus is on microstructure and actual properties (electrical, optical) connected with the deposition procedure of some representative nanocomposite layers. The electrical behaviour of Nd-containing diamond films and the room-temperature emission in the 2.0-2.4 eV region by the Si-containing films are reported and discussed.

Abstract
A new hybrid CVD-powder flowing technique has been adopted in order to grow diamond-based composite materials in form of thin films, coatings and free-standing layers. We report details of the synthesis procedure that allows to control incorporation of nanometer-sized powdered species (metals and semiconductors) in form of aggregates, clusters or nanosized dispersions inside a polycrystalline diamond matrix. The focus is on microstructure and actual properties (electrical, optical) connected with the deposition procedure of some representative nanocomposite layers. The electrical behaviour of Nd-containing diamond films and the room-temperature emission in the 2.0-2.4 eV region by the Si-containing films are reported and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
