Nanoantenna integrated infrared thermoelectric converter

Abstract

Polarization-sensitive, antenna-coupled, monometallic thermocouples were designed, fabricated, and studied for long-wave infrared radiation. The receiving nanoantenna was integrated into the thermocouple, and thermopiles comprising a series combination of ten nanoantennas were constructed. The response showed a cosine square polarization dependence, as expected from antenna theory.
