N2 - The accurate thermal property characterization of micro/nano fibers is crucial for precise micro/nano technology. We developed a non-contact T-type Raman spectroscopy method for combined determination of micro/nano fibers' laser absorption, thermal conductivity and air heat transfer coefficient. The accuracy of laser absorption measurement is independent of the fiber properties or thermal contact resistance. When determining the thermal conductivity, the thermal contact resistance can be easily eliminated. Moreover, the air heat transfer coefficient is determined based on the accurate laser absorption and thermal conductivity data of the same sample. Case studies show that this method is sensitive and accurate for micro/nano fiber characterization.
