这笔赠款支持康奈尔大学购买仪器，用于微/纳米级机电谐振器的低温研究和教育。这一关键仪器将实现对超小型高频谐振结构的低温驱动和检测。纳米级机械结构利用其低质量的优势，有可能实现新的功能和超灵敏传感器技术。优化设备的新设计是这一仪器将使之成为研究的重点之一。接触到内在损耗机制被抑制的低温，应该会导致品质因数显著增加，这是新的高灵敏度器件的基础。新的仪器还将通过电磁、光学或其他方法在低温下实现参数放大。增强的品质因数在帮助暴露非固有设计和工艺相关损失方面至关重要。这些结构的低温性能的优化将对其适用性产生积极的影响，改善其室温性能，并提供重要的教育机会。这些前沿的同时探索将为研究生和博士后助理提供令人兴奋的研究机会，并将为本科生和高中教师提供关于纳米技术的宝贵介绍。这些超小型设备的直观吸引力将在早期阶段吸引学生进入科学领域。我们的计划是接触到这些不同的受众。该仪器本身将是一个完成的挑战，并将为基础科学和先进纳米技术方面的各级研究人员提供一个出色的培训基地，这些技术对我们未来的技术基础设施至关重要。

This grant provides support for the acquisition of instrumentation for low temperature research and education on micro/nano-scale electromechanical resonators at Cornell University. This critical instrumentation will enable low temperature actuation and detection of ultra-small, high frequency resonant structures. Nanoscale mechanical structures have the potential to enable new functionalities and ultra sensitive sensor technology by taking advantage of their low mass. New designs that optimize devices are one of the foci of the research that will be enabled by this instrument. Access to low temperatures where intrinsic loss mechanisms are quenched should lead to a significant increase in the quality factor, a basis of new high-sensitivity devices. The new instrumentation will also enable parametric amplification at low temperatures via electromagnetic, optical, or other methods. The enhanced quality factor is critical in helping to expose non-intrinsic design and process dependent losses. The optimization of the low temperature properties of these structures will positively impact applicability, improve room temperature behavior, and provide significant educational opportunities. The simultaneous exploration of these frontiers will present exciting research opportunities for graduate students and post-doctoral associates and will be a valuable introduction to nano-technology for undergraduates as well as high school teachers. The intuitive appeal of these ultra-small devices will attract students into the sciences at an early stage. Access to these diverse audiences is planned under our program. The instrument itself will be a challenge to complete, and will provide an outstanding training ground for researchers at all levels in the fundamental sciences, and advanced nano-technology that is vital to our future technological infrastructure.
