A novel technique that uses quantum light to measure temperature at the nanoscale

06.05.2019 | Phys.org | www.phys.org

Being able to measure, and monitor, temperatures and temperature changes at miniscule scales—inside a cell or in micro and nano-electronic components—has the potential to impact many areas of research from disease detection to a major challenge of modern computation and communication technologies, how to measure scalability and performance in electronic components.

A collaborative team, led by scientists from the University of Technology Sydney (UTS), developed a highly-sensitive nano-thermometer that uses atom-like inclusions in diamond nanoparticles to accurately measure temperature at the nanoscale. The sensor exploits the properties of these atom-like diamond inclusions on the quantum level, where the limits of classical physics no longer apply.

Temperature monitoring in nanoscale

Diamond nanoparticles are extremely small particles—up to 10,000 times smaller than the width of a human hair—that fluoresce when illuminated with a laser. "The method is immediately deployable. We are currently using it for measuring temperature variations both in biological samples and in high-power electronic circuits whose performance strongly rely on monitoring and controlling their temperature with sensitivities and at a scale hard to achieve with other methods," said Senior Investigator, Dr. Carlo Bradac, UTS School of Mathematical and Physical Sciences.
