Fractal dimensions of the work function and emissivity distributions in a cold cathode

The process of inhomogeneity buildup in distributions of the work function and emissivity on a cathode surface with low initial inhomogeneity under the conditions of field ion-induced electron emission in glow discharge is considered. Estimates of the fractal dimensions of the work function and emis...

Description
Summary:The process of inhomogeneity buildup in distributions of the work function and emissivity on a cathode surface with low initial inhomogeneity under the conditions of field ion-induced electron emission in glow discharge is considered. Estimates of the fractal dimensions of the work function and emissivity distributions on the cathode surface are obtained.
