摘要

我们开发了一种基于光干涉非接触测温法提取有机物/半导体界面热阻（ITR）的实验方法。我们将所提出的技术应用于 SU-8/SiC 双层样品，观察到在脉冲加热和冷却过程中光干涉引起的反射率的明显振荡。将观察到的反射率波形与二维（2D）双层热传导模型和多反射计算的模拟结果拟合后，提取出的 ITR 为 190 mm2 K W-1，这导致界面处的温度下降了 11 K。此外，还获得了样品在整个脉冲加热和冷却过程中的二维瞬态温度分布。

Extraction of interfacial thermal resistance across an organic/semiconductor interface using optical-interference contactless thermometry

We have developed an experimental method to extract interfacial thermal resistance (ITR) at an organic/semiconductor interface based on optical-interference contactless thermometry. The proposed technique was applied to a SU-8/SiC bilayer sample, and clear oscillations in reflectivity induced by optical interference during pulse heating and cooling were observed. After fitting the observed reflectivity waveform with simulation results by a two-dimensional (2D) double-layer heat conduction model and multi-reflection calculations, ITR was extracted as 190 mm2 K W−1, which resulted in a temperature drop of 11 K at the interface. Moreover, the 2D transient temperature distribution of the sample throughout pulse heating and cooling was obtained.
