Summary

Story summary

Researchers at the University of Oldenburg, Germany, report heat transfer between nanometer-scale gaps is about 100 times higher than theory.
The findings, published in Physical Review Letters, challenge theories of thermal radiation such as Planck's law.
The study was led by Prof. Dr. Achim Kittel and Dr. Svend-Age Biehs of the University of Oldenburg, using a refined setup.
The result could advance nanoelectronics and nanooptics by enabling noncontact temperature control.
