论文摘要
我们在实验上证明了表面等离子体极化子（SPP）在玻璃基板上沿薄Ti膜传播的表面上的热传导。由于金属的损失性质，即使使用受支持的金属膜，SPP也可以在厘米尺度的距离上传播，并且可以对产生的弹道热传导进行定量验证。此外，对于玻璃基材上的100 nm厚的Ti膜，与散装值（$ \ sim 35 \％$ $）相比，平面内导热率的显着增强。这项研究将为沿着受支持的薄膜采用SPP的新途径，以减轻微电子的热点问题。
We experimentally demonstrate a boosted in-plane thermal conduction by surface plasmon polaritons (SPPs) propagating along a thin Ti film on a glass substrate. Owing to a lossy nature of metal, SPPs can propagate over centimeter-scale distance even with a supported metal film, and resulting ballistic heat conduction can be quantitatively validated. Further, for a 100-nm-thick Ti film on glass substrate, a significant enhancement of in-plane thermal conductivity compared to bulk value ($\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.
