Emission from Quantum Dots and Lines

The centers of emission can be places of disturbance outlet, borders of grains and phases, germs of new phases. The barium tendency to segregation on these centers leads to formation of a positive charge (potential) and reduction of work function. In this work the emission from quantum-dimensional structures where the emission is determined by the known equation Richardson-Dashman is compared. Density of emission current from unit of the nominal area of the emitter out of places of disturbance outlet to a surface at disturbance density 2middot10¹² m^-2 and from borders of grains at the size of grains 10 microns have one order with current density determined by the equation Richardson-Dashman
