Current-voltage characteristics of carbon nanostructured field emitters in different power supply modes
Source abstract
Abstract
Abstract We received and compared the current-voltage characteristics of large-area field emitters based on nanocomposites with graphene and nanotubes. The characteristics were measured in two high voltage scanning modes: the “slow” and the “fast”. Correlation between two types of hysteresis observed in these regimes was determined. Conditions for transition from “reverse” hysteresis to the “direct” one were experimentally defined. Analysis of the eight-shaped hysteresis was provided with calculation of the effective emission parameters. The phenomenological model of adsorption-desorption processes in the field emission system was proposed.
