The increasing energy demands of the world's population and the quickly diminishing fossil fuel reserves together suggest the urgent need to secure long-lasting alternative and renewable energy resources. Here, we present a THz antenna integrated with a rectifier (rectenna) for harvesting infrared energy. We demonstrate a resonant bowtie antenna that has been optimized to produce highly enhanced localized fields at the bow tip. To benefit from this enhancement, the rectifier is realized between the overlapped antenna's arms using a 0.7 nm copper oxide. The thin film diode offers low zero bias resistance of 500 Ω, thus improving the impedance matching with the antenna. In addition, the rectenna prototype demonstrates high zero bias responsivity (4 A/W), which is critical in producing DC current directly from THz signals without the application of an external electric source, particularly for energy harvesting applications.

ABSTRACTThis work presents the successful production, via a simple oxidation process, of Ti-TiO xPt Metal-Oxide-Metal diodes with excellent electrical asymmetry. TEM analysis has been used to verify the oxide thickness. A thicker layer produces better diodes, although they are of a less uniform nature. The conduction mechanism in these diodes is still under investigation. INTRODUCTIONEnergy recovery systems have attracted much interest in recent years [1][2][3]. A significant amount of energy is wasted in the form of heat, leading to research dedicated specifically to energy recovery from this source. In electromagnetic terms, heat is infrared radiation, and its energy content will follow Planck's Law of spectral distribution. The wavelength of maximum emission intensity λ max within this distribution can be calculated using Wien's Law (Eqn. 1):

“…These so-called rectifying antennas (rectennas) seems to have a great potential in the field of energy harvesting since they exhibit a high theoretical efficiency (claimed to be 100 % [6,7]) and the ability to resonate at anywavelength. In this context, several devices based on nanoantennas coupled to metal-insulator-metal (MIM), metalinsulator-insulator-metal (MIIM) and Esaki tunnel barriers, have been experimentally realized and measured as a proof-ofconcept [12][13][14][15][16][17]. However, in spite of their attractive functionalities, actual rectifying nanoantennas have presented up to now a low efficiency, which is around 10 -9 % [7,8,17].…”
