Description
To investigate and understand the interaction between the surface, bulk material and the electric field, we simulated and studied field emitters by analyzing electro-mechanical and thermal effects, possible interactions between the emitters and dynamic field enhancement factor changes due to the mechanical response of the tips using finite element method. To simulate accurately temperature changes in the emitters, we added nanoscale size effects to thermal and electrical conductivities.
