Keywords:plasmons, local heat, photo thermoelectric effect

Heat generation in metallic nanostructure under plasmon is known as plasmonic local heat, and it has been utilized in various applications, for example, cancer therapy, photohermal chemistry, nanowire growth, and so on. G. Baffou et al. reported that Au single nanoparticle generates local heat about 90 K under the light irradiation of 100 mW/cm2. These facts indicate plasmonic nanostructures will be effective nanoheaters. We came up the idea to utilize the plasmonic local heat as a photo-detector. Here, we propose to combine the local heat of plasmon and the thermoelectric conversion to realize the photo thermoelectric device as a novel photo detector.
