纳米电子材料集成芯片实验室。 A. Haque，宾夕法尼亚州立大学这项研究的目的是开发一种集成芯片实验室型设备，用于电子材料纳米级薄膜的多域表征。该方法是纳米制造具有多功能功能的 3 mm x 3mm x 0.5 mm 尺寸设备，例如用于机械性能的力和位移传感器和执行器以及用于电导率和导热率表征的微电极。智力优点：芯片实验室工具将把当前的范式（单域表征）转变为真正同步的纳米电子材料多域传输研究。 PI 提出，在纳米尺度上，机械应变打破了电子和声子散射的传统规则，从而在物理域之间产生了前所未有的耦合。 PI 将探索极小的长度尺度对这种耦合的作用。极端维度诱导耦合的概念将改变当前对材料物理学的理解，消除了需要特殊原子排列才能表现出任何耦合的先决条件（例如只有中心对称原子才会产生压电），从而开辟材料多物理的新领域。更广泛的影响：通过开展具有挑战性的跨领域实验研究，该研究将弥合纳米结构理论与实验研究之间现有的巨大差距。这项研究的科学发现将开辟下一代纳米电子器件中尺寸和应变可调的电子和声子传输领域。该研究将通过开发研究生教育模块、聘请代表性不足的本科生研究助理以及在州立学院地区学区 K-12 班级中开展外展活动，将研究融入到教育中。

An Integrated Lab-on-a-Chip for Nanoelectronic MaterialsM. A. Haque, the Pennsylvania State UniversityThe objective of this research is to develop an integrated lab-on-a-chip type device for multi-domain characterization of nanoscale thin films of electronic materials. The approach is to nanofabricate a 3 mm x 3mm x 0.5 mm size device with multi-functional capabilities, such as force and displacement sensors and actuator for mechanical properties and micro-electrodes for electrical and thermal conductivity characterization. Intellectual Merits: The lab-on-a-chip tool will transform the current paradigm (single-domain characterization) to truly simultaneous multi-domain transport studies on nanoelectronic materials. The PI proposes that at the nanoscale, mechanical strain breaks down the conventional rules for scattering of electrons and phonons, giving rise to unprecedented coupling among physical domains. The PI will explore the role of extremely small length-scales on such coupling. The concept of extreme dimension-induced coupling will transform the current understanding in materials physics by removing the pre-requisite that special arrangement of atoms are required to exhibit any coupling (such as only centro-symmetric atoms lead to piezo-electricity) and thereby open a new area of multi-physics of materials. Broader Impacts: By enabling challenging cross-cutting experimental studies, the research will bridge the existing wide gap between theoretical and experimental studies on nanostructures. The scientific findings of this research will open the area of dimension and strain tunable electron and phonon transport in next generation nanoelectronic devices. The research will be integrated to education by developing education modules at the graduate level, hiring under-represented undergraduate research assistants and performing outreach activities in the State College area school District K-12 classes.
