An Integrated Lab-on-a-Chip for Nanoelectronic Materials

一种用于纳米电子材料的集成化芯片实验室。A.哈克，宾夕法尼亚州立大学这项研究的目标是开发一种集成的芯片上实验室类型的设备，用于电子材料纳米级薄膜的多域表征。该方法是将尺寸为3 mm x 3 mm x 0.5 mm的设备纳米化，具有多功能功能，如用于机械性能的力和位移传感器和致动器，以及用于表征电导和热导率的微电极。智能优势：芯片实验室工具将把目前的范式(单域表征)转变为真正同时进行纳米电子材料的多域传输研究。PI提出，在纳米尺度上，机械应变打破了电子和声子散射的常规规则，导致了物理域之间前所未有的耦合。PI将探索极小的长度尺度对这种耦合的作用。极维诱导耦合的概念将改变目前材料物理学的理解，因为它消除了原子的特殊排列才能表现出任何耦合的先决条件(例如只有中心对称的原子才能产生压电性)，从而开辟了材料多物理的新领域。更广泛的影响：通过使具有挑战性的交叉实验研究成为可能，该研究将弥合纳米结构理论研究和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维度和应变可调的电子和声子输运的领域。这项研究将通过在研究生一级开发教育模块、雇用任职人数不足的本科生研究助理以及在州立大学区学区K-12班级开展外联活动，纳入教育。

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.
