Modeling and calculation of nanostructural field emission triode characteristics

The technology for manufacturing field emission diodes based on nanoporous anodic alumina (AA) can be easily supplemented with a number of appropriate operations for forming grid electrodes and, finally, for creating field emission triodes (FETs). The structure of the FET consists of a regular array of uniform cylindrically shaped field emission triode cells (FETCs), the outer diameter of which is equal to that of oxide cells (OCs) of AA, and their packing density corresponds to that of OCs which can be varied ranging from 10⁸ to 10¹¹ OC/cm² by selecting the appropriate anodizing regimes. To model FET characteristics of the above-mentioned structure a computer program of their analysis comprising a few stages has been developed. At the first stage the electrostatics task was solved in a single cell, that resulted in estimating describing a charge transfer process inside the triode structure were solved, and on the basis of the obtained results I-V characteristics were calculated
