Notes:
Field-emission current from chemical vapor deposited diamond film on molybdenum wafer has been investigated experimentally and theoretically. The Fowler–Nordheim plot exhibits three linear regimes, corresponding to low, middle, and high electric field, respectively. A potential barrier model, based on a fact that metal carbide, Mo2C, exists at the interface between diamond and substrate, is presented. In terms of this model, the expression of field-emission current from diamond on Mo has been derived. The theoretical results agree qualitatively with the experimental observation and indicate that the emission current is related to the thickness of Mo2C and diamond under low and middle electric field, however, no similar relationship is found under high field. © 1998 American Institute of Physics.
