“…This has two major outputs: (a) this supports the hypothesis that their response is due to AC rectification, not a bolometric effect, as will be shown later, and (b) it can be said that the output assuming an unpolarized source will be different from that from a fully-or partially-polarized source [94]. The experiments in support of the polarization-dependent response of the rectenna are many, such as those of [45,95,96]. Bareiß et al [96] have experimentally ensured the polarization-dependent response of the rectenna system reaching a polarization ratio of seven times in their experiment.…”

“…The experiments in support of the polarization-dependent response of the rectenna are many, such as those of [45,95,96]. Bareiß et al [96] have experimentally ensured the polarization-dependent response of the rectenna system reaching a polarization ratio of seven times in their experiment. Fumeaux et al [28] have also concluded a polarization-dependent response of the rectenna system at 30 THz, but it should be noted that it was assumed to be composite, i.e., resulting from both tunneling and thermal effects.…”

“…In fact, experiments' output might be considered helpful to answer this question. The output of the experiment conducted by Bareiß et al [96] addresses this issue such that the I(V) characteristics of the fabricated diode could refer to the actual theory of operation. The fabrication process resulted in operating antennas (meaning having the expected output response) and defect antennas.…”

“…While the works of [84,96,101,103] rely on the Seebeck effect to explain their results and obtain accurate models, Fumeaux et al [28] and Heiblum et al [46] attribute the output of their experiments to thermal-assisted tunneling. It should be noted, however, that Heiblum et al [46] state in their paper that "lower impedance junctions had less thermal contributions than the high impedance ones"; which holds true for the experiment results of Seebeck effect model even with a different cause.…”

Abstract:The increasing demand for more efficient energy harvesting solutions has urged research for better harvesting solutions than the presently-available ones. While p-n junction solar cells have become commercially widespread, they are expensive and suffer from poor efficiency figures hardly reaching 20%. Other radiation-electricity converters such as rectennas have a theoretical limit in excess of 80%. However, no efficient rectenna solution for the terahertz frequency band has been commercialized or presented in the academic literature. In fact, there are many obstructions to an efficient solution. The aim of this paper is to address the key points towards an efficient and commercially-available solution by briefly reviewing the relevant literature and so identifying five factors that should be addressed in order to reach an efficient solution.

Numerical conversion efficiency of thermally isolated Seebeck nanoantennas

et al. 2016

In this letter, we evaluate the conversion efficiency of thermally isolated Seebeck nanoantennas by numerical simulations and discuss their uses and scope for energy harvesting applications. This analysis includes the simple case of titanium-nickel dipoles suspended in air above the substrate by a 200 nm silicon dioxide membrane to isolate the heat dissipation. Results show that substantially thermal gradients are induced along the devices leading to a harvesting efficiency around 10-4 %, 400 % higher than the previously reported Seebeck nanoantennas. In the light of these results, different optimizing strategies should be considered in order to make the Seebeck nanoantennas useful for harvesting applications.
