- Abstract
Carbon nanotubes (CNTs) have been studied using a field electron microscope (electron projector) and a dispersive electron energy analyzer. In the range of emission voltages studied, the field-emitted electron energy distributions showed periodic transformations. The corresponding probe current-voltage characteristics exhibited periodic deviations (reaching 20 and 50% for the two CNT samples studied) from the Fowler-Nordheim law toward lower values of the current. The observed phenomenon is explained in terms of the interference model of thermoelectron emission at high voltages.
