The computer model of field electron emission from emitter-arrays in MATLAB is proposed. Physical and mathematical models, computational methods and algorithms of the program complex are presented. Electrostatic simulation of electron transport processes with PDE Toolbox finite element solutions is implemented in MATLAB stand-alone application with graphical user interface. The simulation results by the example of two different diode structures are presented. Two generic cone-shape and wedge-shape non-gated emitter-array diodes are considered. The effects of the variations in device geometrical structure and parameters on its potential distribution, electric field, and emission current are discussed. The current variation rate with respect to the tip-collector distance is calculated. Bibliogr. 7. Il. 5.
Keywords: field electron emission, field emitters array, MATLAB PDE Toolbox.
