摘要
A study has been made of the field-emission characteristics of cerium and BaO films on W within a broad range of field-emission currents and fields. An anomalous broadening of the spectra and a deviation of Fowler-Nordheim characteristics from linearity have been revealed for high (above 10(9) A/m(2)) field-emission current densities. The dependence of this anomalous behavior of field-emission characteristics on the work function and topography of the surface has been investigated. Possible reasons for the observed phenomena are discussed. (C) 1999 American Institute of Physics. [S1063-7834(99)03404-8].
