摘要：

A carbon (PAN) fiber crystal was studied in a field electron microscope equipped with a dispersive energy analyzer. Annealing of the emitter crystal at a temperature of 750° C lead to a tenfold decrease in the emission current and to the appearance of an additional low-energy peak (shifted by 0.5 eV from the main peak toward lower energies) in the field electron energy distribution. An increase in the anode voltage restored both the initial emission current and the electron energy distribution.
