Nanofilms Optimize Raman Thermometry for Extreme Manufacturing
AMES, Iowa, Sept. 29, 2022 — Researchers at Iowa State University, Shenzhen University, and Shanghai University of Engineering Science demonstrated an approach to the thermal probing of nanomaterials in which the ratio of two resonance Raman peak intensities of a 2D material, tungsten disulfide (WS2), could be used as an indicator for high-sensitivity temperature measurements. Traditional Raman spectroscopy-based temperature sensing typically tracks the change of Raman wave number, linewidth, and intensity. The
