Researchers in Mexico fabricated and compared bimetallic Ni-Pt nanoantennas for a classic and evolutive dipole configuration. Observing the thermoelectric voltage dependence associated with classic and evolutive dipole configuration they found that the evolutive dipole nanoantennas (EDN) generate up to three times more voltage in contrast with the classic dipole nanoantenna (CDN). The evolutive configuration is 1.3 times more efficient than its classical counterpart. The results are corroborated by absorbance of these nanoantennas in the 20 to 36 THz range, where EDN is 40% more efficient than CDN and 30% in the range of 36.1 to 90 THz…read more.
