项目摘要
With the coming era of the Internet-of-Things (IoT), there is an increasing need for miniaturized smart devices, such as smart sands, tags, and wearable/implantable devices, for various biomedical and environmental monitoring applications. Many critical components in these devices, such as sensors, antennas, inter-connects and batteries are not compatible with conventional Integrated Circuits (IC) processes used in the semiconductor industry. In addition, many devices need to be customized for their specific target applications, which could require three-dimensional nanostructures, heterogeneous materials integration, miniaturized form factor, and specified sensitivity, power density and life times. It is difficult for conventional semiconductor manufacturing foundries to accommodate these customized specifications due to the lack of flexibility in process and material choices. Micro and nanoscale additive manufacturing has the potential to meet such requirements. However, a technical breakthrough is still needed in this area to enable additive manufacturing of functional components with nanoscale resolution, quality and reliability commensurate with IC fabricated devices. This award supports fundamental research to form the knowledge base for development of nanoscale additive manufacturing (Nano-AM) processes for direct manufacturing of nano-devices. Multiple disciplines are involved in this research including nanomanufacturing, laser-nanomaterial interaction, surface science, and multiscale transport phenomena. Results from this research will enhance the U.S. competence in advanced manufacturing industry by providing paradigm-changing manufacturing technique in the era of IoT. The integration of the research results into curriculum development, undergraduate and minority students research opportunities and hands-on projects for K-12 students will enhance the students' knowledge and foster innovation in advanced manufacturing.Current nanoscale additive manufacturing is limited by the lack of capability to fabricate 3D nonpolymer functional devices. To overcome this limit, this research employs non-polymer (metal, semiconductor and dielectric) nanomaterials as building blocks and aims at understanding and exploiting unique behaviors of these nanomaterials under ultrafast laser excitation to enable 3D Nano-AM processes. Firstly, fundamental mechanisms leading to femtosecond laser induced ionization and surface modification of nanomaterials will be explored. Secondly, the correlations between laser excitation (ionization and modification) and induced nanomaterial assembly, deposition and sintering behaviors will be established. Multiscale modeling and simulations (Ab initio, classical Molecular Dynamics and Brownian Dynamics) will be performed to understand experimental results over different temporal and spatial scales. Finally, a physics-based model relating nanomaterials properties, laser excitation conditions with the morphology and properties of manufactured nanostructures will be developed.
随着物联网(IoT)时代的到来,对小型化智能设备的需求越来越大,例如智能砂、标签和可穿戴/可植入设备,用于各种生物医学和环境监测应用。这些设备中的许多关键部件,如传感器、天线、互连和电池,与半导体行业中使用的传统集成电路(IC)工艺不兼容。此外,许多设备需要针对其特定的目标应用进行定制,这可能需要三维纳米结构、异质材料集成、小型化的形状因数以及特定的灵敏度、功率密度和寿命。由于在工艺和材料选择上缺乏灵活性,传统的半导体制造工厂很难适应这些定制的规格。微米和纳米级的添加剂制造有潜力满足这些要求。然而,在这一领域仍然需要技术突破,以实现与IC制造设备相称的纳米级分辨率、质量和可靠性的功能部件的附加制造。该奖项支持基础研究,以形成开发用于直接制造纳米器件的纳米级添加剂制造(Nano-AM)工艺的知识库。这项研究涉及多个学科,包括纳米制造、激光-纳米材料相互作用、表面科学和多尺度传输现象。这项研究的结果将通过提供物联网时代改变范式的制造技术来提高美国在先进制造业中的竞争力。将研究成果整合到课程开发、本科生和少数民族学生的研究机会以及面向K-12学生的实践项目中,将增强学生的知识,促进先进制造的创新。目前纳米级添加剂制造受到缺乏制造3D非聚合物功能器件的能力的限制。为了克服这一限制,本研究使用非聚合物(金属、半导体和介电)纳米材料作为构建块,旨在了解和利用这些纳米材料在超快激光激励下的独特行为,以实现3D Nano-AM工艺。首先,对飞秒激光诱导电离和纳米材料表面修饰的基本机理进行了探讨。其次,将建立激光激发(电离和修饰)与诱导纳米材料的组装、沉积和烧结行为之间的关联。多尺度模拟和模拟(从头算、经典分子动力学和布朗动力学)将被用来理解不同时间和空间尺度上的实验结果。最后,将开发一个基于物理的模型,该模型将纳米材料的性质、激光激发条件与所制造的纳米结构的形态和性质联系起来。
