Abstract

Nanocluster carbon thin films were grown using the room temprature based cathodic arc process. These films are mixed phase material containing both sp2 and sp3 bondings. Space-charge-limited-current conduction (SCLC) mechanism was investigated in the case of Nanocluster carbon thin films. The results were analyzed by assuming uniform density of traps near the Fermi level. The values of density of states at the obtained from the SCLC measurements ranges between 6x1017 cm-3 eV-1 to 8x1017 cm-3 eV-1.
