界面热导在微纳米器件热传导中具有重要作用,理解如何调节界面热导至关重要.本文采用瞬态热反射技术,研究固体界面间不同浓度的罗丹明6G溶液对界面热传导的影响.测量结果显示,随着界面间罗丹明6G溶液浓度的增加,Al/Si O2界面热导呈现对数减少的趋势.文中建立的理论模型,可预测界面热导与罗丹明6G覆盖面积之间的关系,这有利于选择合适浓度的罗丹明6G溶液来进行调节界面热导的热设计.
It is very important to understand how to adjust the thermal conductance of the interface.This paper uses the transient heat reflection technique to study the influence of different concentrations of rhodamine 6G solution on the interface thermal conductivity at the interface of solid state.The results Shows that the logarithm of the thermal conductivity of Al / Si O2 tends to decrease logarithmically with the increase of the concentration of 6D rhodamine 6.The theoretical model established in this paper can predict the relationship between the interface thermal conductivity and the coverage of rhodamine 6G, This facilitates the choice of a suitable concentration of rhodamine 6G solution for the thermal design of the interface thermal conductivity.
