The responsivity and frequency dependence of three types of Seebeck nanoantennas is obtained by electromagnetic simulation for different materials. Results show that the square spiral antenna has the widest bandwidth and the highest induced current of the three analyzed geometries. However, the geometry that presented the highest temperature gradient was the bowtie antenna, which favors the thermoelectric effect in a Seebeck nanoantenna. The results also show that these types of devices can present a voltage responsivity as high as 36  μV/W36  μV/W for titanium–nickel dipoles resonant at far-infrared wavelengths.engjournal articlehttp://dx.doi.org/10.1117/1.JPE.6.024501http://photonicsforenergy.spiedigitallibrary.org/article.aspx?articleid=2520464open access537.533.3620.91621.396.67Seebeck nanoantennasthermoelectric nanoantennassolar energy harvestingElectromagnetismoÓptica (Física)Optoelectrónica2202 Electromagnetismo2209.19 Óptica Física
