New research paper on Super-Planckian Radiative Heat Transfer published

Researchers from the School of Engineering at Arizona State University have published a research study detailing the development of a new experimental method that will facilitate the potential applications of near-field radiative devices. This development will support applications ranging from, thermal imaging, thermopower conversion, radiative cooling, to contactless heat flow management such as thermal rectification and modulation. The research paper is authored by Xiaoyan Ying, Payam Sabbaghi, Nicole Sluder, and Liping Wang.

This experimental method has explored the near-field thermal radiation enhancement between highly doped silicon chips over the blackbody limit. The focus was to analyze the heat transfer between the silicon chips at different arrangements. For these various arrangements, their respective radiative heat flux values were calculated with our gSKIN sensors (the gSKIN XP-26-9C). These heat flux values eventually set the grounds for calculating the heat transfer between the silicon chips to uncover the most suitable chip arrangement.

Ultimately, experimental results were validated by theoretical calculations based on fluctuational electrodynamics, which revealed the enhancement mechanism (arrangement) to be mainly as a ‘coupled surface plasmon polariton’.

We would like to congratulate the authors for their great efforts towards this achievement, and we welcome you to explore more on our expertise and sensor solutions on our webpage and on our product pages in our webshop.
