Abstract:
1. A field emission device comprising two electrodes, each electrode symmetrically opposed to each other and further comprising: a. an electrically conductive layer; b. a dielectric interface layer positioned directly over the electrically conductive layer; and c. a plurality of electrically conductive islands attached on one exposed surface of the dielectric interface layer opposite the electrically conductive layer; wherein said electrically conductive islands of each electrode alternatively emit electrons and collect electrons as a voltage between said electrically conductive layers changes as a function of time; said dielectric interfaces causing capacitance which divides current caused by said electrons to be evenly between said islands, spreading the current from said islands to a larger area of said electrically conductive layers, thereby reducing heating in said device, and regulating the current from said islands by their capacitive reactance.
