Chemical Thermometers Take Temperature to the Nanometric Scale
Scientists from the Coordination Chemistry Laboratory and Laboratory for Analysis and Architecture of Systems, both of the CNRS, recently developed molecular films that can measure the operating temperature of electronic components on a nanometric scale. These patented temperature-sensitive molecules have the distinctive quality of being extremely stable, even after millions of uses. They were presented in an article published in Nature Communications on 17 July 2020, and could soon be deployed in the microelectronics industry.
The miniaturisation of electronic components coupled with their increasing integration density has considerably expanded heat flows, which can lead to overheating. But how to measure these nanometric events when conventional solutions such as infrared thermography cannot go below a micrometre (1,000 times bigger than a nanometre)?
