Metal-insulator-metal (MIM) or metal-insulator-insulator- metal (MIIM) diodes are incorporated with micron-scale antennas in optical rectennas for converting infrared radiation into electrical power. They are suited for such an application due to their high frequency rectification properties1 and relatively low cost, as compared to diodes formed on single crystal substrates. Their rectification characteristics, as determined from direct current (DC) current-voltage [I(V)] measurements, are usually inferior to those of semiconductor diodes.
