摘要：
我们通过实验证明，沿玻璃衬底上的薄Ti膜传播的表面等离激元极化子（SPPs）可增强面内热传导。由于金属的损耗特性，即使在有衬底的金属膜上，SPPs也能传播厘米级距离，且由此产生的弹道热传导可得到定量验证。此外，实验表明，对于玻璃衬底上100纳米厚的Ti膜，其面内热导率较块体值显著提升（约35%）。本研究为利用SPPs实现有衬底薄膜的散热提供了新途径，可直接应用于缓解微电子器件中的热点问题。
英文摘要：
We experimentally demonstrate a boosted in-plane thermal conduction by surface plasmon polaritons (SPPs) propagating along a thin Ti film on a glass substrate. Owing to a lossy nature of metal, SPPs can propagate over centimeter-scale distance even with a supported metal film, and resulting ballistic heat conduction can be quantitatively validated. Further, for a 100-nm-thick Ti film on glass substrate, a significant enhancement of in-plane thermal conductivity compared to bulk value ($\sim 35\%$) is experimentally shown. This study will provide a new avenue to employ SPPs for heat dissipation along a supported thin film, which can be readily applied to mitigate hot-spot issues in microelectronics.
