Abstract: 

Results of numerical simulation of electron field emission from the surface of 2-D fractal object bounded by Julia set are presented. The calculations show that emission occurs mainly from small sites of the surface close to self—similar small-scale irregularities, where the electrostatic field is ampiified greatly. Submitted results confirm hypothesis, that unusual field—emission properties of some materials could be explained by taking into account the fractal structure of its surface. The influence of ihe fractal dimension on the emission has been cleared. It turned out that emission current depends mainly on the geomeiry of small-scale irregularitics. Nevertheless, the fractal dimension defines the slope of current—voltage characteristics.
