GOALI: ELASTIC WAVE RESONATORS

摘要：目前用于计量的技术受到测量速度慢、易受表面相互作用影响的困扰，并且某些技术甚至可能由于表面上的尖端磨损而使测量表面变形。开发新的工具来应对这些挑战可能会在纳米计量学和纳米结构组装领域开创一个新时代。这种系统在电子学、光学和生物学应用领域具有重要意义。这项综合研究和教育GOALI提案围绕弹性波谐振器的开发以及Ag2Ga纳米针和光机械致动器的集成，以实现纳米操纵，纳米计量和纳米组装的精确工具。弹性波谐振器的原理是一种方法，通过该方法，单个和多维驻波沿着高纵横比的微尺度细丝以kHz至MHz的速率传播。与细丝的柔性和刚度相比，包含在“波包”内的能量的大小使得能够产生明显的驻波，并且沿着细丝维持驻波。该提案的目标是调查使用纳米级驻波探针谐振器的计量，了解机电限制和缩放问题，这种谐振器，开发数学模型和开发应用程序在纳米组装。该提案的教育方面是利用研究为基础的本科课程在纳米机械谐振器，在工业现场实习，研究生水平的课程纳米机械谐振器，并为代表性不足的学生在这个令人兴奋的领域的机会。

Abstract: Current techniques used for metrology are plagued by slow measurement speed, susceptibility to surface interactions, and some techniques can even deform the measured surface due to tip wear on the surface. Development of new tools to address these challenges could spawn a new era in the area of nano-metrology, and nano-assembly of structures. Such systems can have significance in the area of electronics, optical, and biological applications. This integrated research and education GOALI proposal centers around the development of elastic wave resonators and integration of Ag2Ga nano-needles and photomechanical actuators to enable precise tools for nanomanipulation, nano-metrology and nano-assembly. The principle of elastic wave resonators is a method by which single and multidimensional standing waves propagate at a rate of kHz to MHz along a high aspect ratio micro-scale filament. The magnitude of energy contained within the "wave packet" compared to the flexibility and stiffness of the filament enable pronounced standing waves to be generated and sustained along the filament. The proposal objectives are to investigate the use of nanoscale standing wave probe resonators for metrology, understand the electro-mechanical limits and scaling issues of such resonators, develop mathematical models and develop applications in nano-assembly. The educational aspects of the proposal are utilizing research based undergraduate course in nano-mechanical resonators, internships at industrial sites, graduate level course on nano-mechanical resonators, and opportunities for underrepresented students in this exciting area.
