Physical considerations of operating and characteristics modeling of nanostructural field emission devices

In this paper, the characteristics of nanostructural field emission devices (FEDs) are determined based on a basic model that is a field emission triode cell which has more complicated structure compared with a diode. The basic elements of a field emission triode cell was characterized using the following parameters; conductor elements, dielectric elements, the boundary of a field emission triode cell, and an electron gas region or vacuum region. Physical processes was described by means of the fundamental equations of Maxwell, Fowler-Nordheim and hydrodynamical equations describing the behaviour of electron gas.
