Proposal No: 304218Title: NER: Carbon Nanotube based Nano-Electromechanical ResonatorsCarbon Nanotube Nanoelectromechanical ResonatorsAbstractThis nanoscale exploratory research (NER) project centers around the development of high frequency nano-electro-mechanical (NEMS) resonators using carbon nanotubes. Carbon nanotubes are ideal for NEMS due to their high strength, high elastic modulus, high thermal conductivity, low density, and ability to be synthesized with different lengths and diameters. The proposed resonators are fabricated by aligning single wall carbon nanotubes on nano-lithographically patterned substrates creating a doubly clamped resonating structure, with expected resonance frequencies greater than 1 GHz. If successful, the project will lead to the development of sensors for precise detection of extremely small forces, displacements, masses, and chemical molecules. Creation of efficient antennas much smaller than a wavelength by using the mechanical resonance to accelerate charges can create a new approach for designing antenna arrays for future military, space, and wireless applications. The educational impacts of the project stem from the interdisciplinary nature of this research that involves nanotechnology, electromagnetics, and molecular structural mechanics, thereby creating a new area called "Nano-Electromagnetics". A graduate course on NEMS, utilization of undergraduate research programs, and collaborative opportunities between academic and industrial researchers are expected to create excellent awareness of and access to this new technology.

提案编号：304218标题：NER：碳纳米管纳米机电谐振器碳纳米管纳米机电谐振器摘要这个纳米级探索性研究（NER）项目围绕着使用碳纳米管的高频纳米机电（NEMS）谐振器的发展。碳纳米管由于其高强度、高弹性模量、高导热性、低密度以及能够以不同长度和直径合成而成为NEMS的理想选择。 所提出的谐振器是通过在纳米光刻图案化的衬底上对齐单壁碳纳米管来制造的，从而产生双箝位谐振结构，预期谐振频率大于1 GHz。 如果成功，该项目将导致传感器的发展，用于精确检测极小的力，位移，质量和化学分子。 通过使用机械谐振来加速电荷来创建比波长小得多的高效天线，可以为未来的军事，空间和无线应用设计天线阵列创造一种新的方法。 该项目的教育影响源于这项研究的跨学科性质，涉及纳米技术，电磁学和分子结构力学，从而创建了一个称为“纳米电磁学”的新领域。 NEMS研究生课程，本科研究计划的利用，以及学术和工业研究人员之间的合作机会，预计将创造良好的认识和获得这一新技术。
