Abstract
The field emission properties from diamond films grown under substrate bias conditions in a microwave plasma CVD system were investigated, with a substrate temperature of 800 °C, microwave power of 600 W and a total pressure of 11 Torr. One group of films was grown with a substrate bias at -100 V in a gas mixture of 1% N2, 1% to 20% CH4 in H2, while a second group of films was grown with a substrate bias ranging from 100 V to -150 V in a gas mixture of 1% N2-10% CH4-89% H2. Field emission performance in terms of turn-on field and emission current improved considerably as CH4 concentration and negative bias voltage increase.
