鉴于这些宏观材料在基础科学和技术应用中的巨大价值,以及现有实验方法和商业设备存在的诸多局限和挑战,北京大学宋柏研究员团队于2023年初提出Big-MEMS热测量新概念,以填补这一显著的研究空白。 图1:Big-MEMS热测量方法示意图[1] Big-MEMS概念的核心是...
这一系列结果充分凸显了Big-MEMS方法在热输运精密测量领域的重要价值。 图5:本征硅热导率测试[2] Big-MEMS概念原则上还可以拓展应用到热扩散率、比热乃至电荷输运等更为广泛的测量对象,在诸如低维材料发散热导率以及表面电磁模式热传导等奇异输运机制的探索中提供独特的实验支撑。综上所述,该研究进展既有望推动先进...
In this study, we address these challenges by building upon the recently proposed concept of big-MEMS for thermal measurement. At the core of our approach is a suite of suspended devices fabricated from low-stress silicon nitride (SiNx) nanofilms with integrated platinum resistive heater/...
