Abstract
A resistive switching device includes a substrate; a first dielectric layer on the substrate; a conductive via in the first dielectric layer; a bottom electrode on the conductive via and the first dielectric layer, a resistive switching layer on the bottom electrode; and a cone-shaped top electrode on the resistive switching layer. The cone-shaped top electrode can produce increased and concentrated electric field during operation, which facilitates the filament forming process.
