Abstract

We present the thermal study of micro thermocouples fabricated by electron beam lithography process, the micro thermocouples (MTCs) are based on a recently discovered thermoelectric effect in single-metal nanostructures with cross-sectional discontinuity, single-metal MTCs would simplify the fabrication process and allow the large-scale production of these devices using fabrication technologies such as nanoimprint lithography. In this work, we have investigated the temperature difference between the asymmetric unions of the micro thermocouples using Optotherm EL InfraSight 320 thermal imaging camera. Results show that single-metal MTCs are promising structures that could be used to harvest thermal radiation and generate electric energy through the Seebeck effect.
