Abstract
Today, nano-sized capacitors are widely used for storage of electric energy. Consequently, it’s too important the knowing how to estimate their capacitance theoretically. This can’t be done based on the standard formula useful for macroscopic capacitors with bulk dielectric layers. There is proposed a new formula determining nanocapacitance from effective permittivity and effective thickness of the nanofilm dielectric placed between the nanocapacitor plate-electrodes. This formula explains how the capacitance of a nanocapacitor may significantly differ from its geometric value.
