It has been observed that the emission properties improve when the absolute value of self\-bias voltage becomes higher, e.g., the turn\-on field value decreases. The correlation between electron field emission and sp2 content in these films showed improvement of electron emission properties of DLC films for higher amount of sp2 phase."]
