Optothermal
WebOptothermal Raman (OTR) is a steady-state measurement technique, which directly determines thermal conductivity of a film. In this technique the Raman excitation laser acts as a heater to induce local heating in the film and micro Raman spectrometer is used as thermometer to determine this local temperature rise. WebMay 13, 2024 · The thermal conductivity of NMO films was determined by optothermal Raman method based on an approximately isothermal surface condition. Irrelevant to the film thickness and the grain size, the derived thermal conductivity is kept nearly constant as ∼4.0 ± 0.8 W m −1 K −1., indicating that thermal conductivity mainly arises from the ...
