Electron emitting nanostructures of carbon plus Pd system

A system of nanometer sized Pd crystals in fullerenes was grown by thermal deposition of fullerenes C-60/C-70 mixture (C-60:C(70)ratio was 8:2) and Pd organic compound from two separated sources. Films were deposited on the v arious substrate (fuse silica, copper band, molybdenum band and semiconduct ing Si). Obtained films were studied by TEM, ED, SEM and ESCA methods showi ng that films are composed of 2.5nm Pd clusters situated in fullerenes matr ix. The bias voltage applied along the film caused the creation of electric al conductivity paths. After the formation of electrical conductivity path electron emission was observed for film (on fused silica) placed in diode s ystem. These paths were formed of the nanometer sized Pd crystals. As a res ult of such structural changes we observed enhanced field emission from the film.
