With a large-area field electron emitter, when an individual post-like emitter is sufficiently resistive, and current through it sufficiently large, then voltage loss occurs along it. This conference presentation provides a simple analytical and conceptual demonstration that this voltage loss is directly and inextricably linked to a reduction in the field enhancement factor (FEF) at the post apex,...
We report the featured field electron emitter of Si tip with individually integrated nano-channel. A rational procedure was developed to fabricate the uniform integrated device. The Si nano-channel can limit both current and heat flow. The heat resistance of the nano-channel resulted in the heat accumulation at the tip apex, inducing the thermally assisted field electron emission. The negative feedback...
The paper discusses the conditions of occurrence of the thermal field emission of electrons from CNTs in additions to field emission. The temperature of emitting CNT end was calculated. An experiment was also carried out using single multi-walled nanotube in which the region of I-V characteristic associated with thermal field emission was observed.
A theoretical model for one-dimensional CuO nanowire was established considering transport mechanisms induced by different defect concentration. By using a one-dimensional heat equation, the emission current was calculated by considering the temperature induced by the emission current. The maximum emission current density and maximum applied field was studied considering different electrical properties...
