The metal-insulator-metal (MIM) diodes have high speed and compatibility with integrated circuits (IC’s) making MIM diodes very attractive to detect and harvest energy for infrared (IR) regime of the electromagnetic spectrum. Due to the fact that small size of the MIM diodes, it is possible to obtain large volume of devices in same unit area. Hence, MIM diodes offer a feasible solution for nanorectennas (nano rectifiying antenna) in IR regime. The aim of this study is to design and develop MIM diodes as array format coupled with antennas for energy harvesting and IR detection. Moreover, varying number of elements which are 4x4, and 40x30 has been fabricated in parallel having 0.040, 0.065 and 0.080 μm² diode area. For this work we have studied given type of material; Ti-HfO₂-Ni, is used for fabricating MIM diodes as a part of rectenna. The effect of the diode array size is investigated. Furthermore, the effect of the array size is also investigated for larger arrays by applying given type of material set; Cr-HfO₂-Ni. The fabrication processes in physical vapor deposition (PVD) systems for the MIM diodes resulted in the devices having high non-linearity and responsivity. Also, to achieve uniform and very thin insulator layer atomic layer deposition (ALD) was used. The nonlinearity 1.5 mA/V² and responsivity 3 A/W are achieved for Ti-HfO₂-Ni MIM diodes under low applied bias of 400 mV. The responsivity and nonlinearity of Cr-HfO₂-Ni are found to be 5 A/W and 65 μA/V², respectively. The current level of Cr-HfO₂-Ni and Ti-HfO₂-Ni is around μA range therefore corresponding resistance values are in 1-10 kΩ range. The comparison of single and 4x4 elements revealed that 4x4 elements have higher current level hence lower resistance value is obtained for 4x4 elements. The array size is 40x30 elements for Cr-HfO2-Ni type of MIM diodes with 40, 65 nm² diode areas. By increasing the diode area, the current level increases for same size of array. The current level is increased from10 μA to100 μA with increasing the diode area. Therefore resistance decreased in the range of 10 kΩ and nonlinearity is increased from 58 μA/V² to 65 μA/V².
