Undoped diamond-like carbon thin films grown by direct current-plasma enhanced chemical vapour deposition: structural and electrical properties
Undoped diamond - like carbon thin films have been grown by DC - PECVD system. The synthesis of the DLC films was carried out in the presence of gas of (CH4 + H2 + Ar) in a custom - made reactor. The substrate temperature was initiated from the range of 300 °C to 600 °C under an optimum pressurized...

| Summary: | Undoped diamond - like carbon thin films have been grown by DC - PECVD system. The synthesis of the DLC films was carried out in the presence of gas of (CH4 + H2 + Ar) in a custom - made reactor. The substrate temperature was initiated from the range of 300 °C to 600 °C under an optimum pressurized medium. The AFM image reveals that the optimization of DLC films growth at the substrate temperature 400 °C has a significant surface roughness and average grain size which is compatible to the result of film thickness measurement. The sample J400 shows an excellent nonlinear rectifying diode-like characteristic across the small potential difference. |
