Metal-insulator-metal (MIM) diodes are very promising for application as rectennas for solar energy harvesting, photo-detectors and high frequency mixers. Good MIM diode performance requires a high asymmetry, a strong nonlinearity, a large responsively, as well as a low resistance or a high on-current. These figures of merit are mainly determined by the work function difference of the electrodes, and the barrier height between the insulator and the electrode materials. In the design of MIM diodes, ...
