项目摘要

This award will develop theoretical and computational models, and experimental methods to advance the fundamental understanding on the mechanics of multilayered van der Waals materials and heterostructures. Such materials and structures have promising applications such as novel detectors, sensors and quantum emitters. The van der Waals materials are considered an important class of quantum materials, critically important for the imminent second quantum revolution (Quantum 2.0). It has been recognized that the presence of strain in the van der Waals materials can profoundly influence their electronic and optical properties, and the strain could be used to tune their physical properties, thus presenting an opportunity for mechanics. To materialize these applications, one must understand the van der Waals interactions between various types of two-dimensional materials and the mechanics governing the strain distributions. If successful, this research would advance the mechanics of materials research to the forefront of the second quantum revolution, opening new opportunities by controlling and manipulating individual quantum systems. The project will provide excellent research and education opportunities for graduate and undergraduate students, and promote diversity by recruiting and mentoring students from underrepresented groups.The objectives of the research include: (i) The development of a theoretical framework for the mechanics of multilayered van der Waals (vdW) materials, based on atomistically informed potential energy functions for the vdW interactions between 2D materials, coupling adhesive normal interactions with periodic shear interactions; (ii) The development of computational models for twisted and strained bilayer vdW materials, including pressurized micro-blisters with inhomogeneous deformation; (iii) The development of multiscale experimental methods to characterize the vdW interactions between various 2D materials. The intellectual merit of the research arises from the integration of theoretical and computational modeling with novel experiments in order to investigate the mechanics of multilayered vdW materials and heterostructures. The multiscale modeling approach complements the first-principles based atomistic models and has the advantage of scaling up for larger systems. Correspondingly, multiscale experiments will be developed, from nanoribbons to micro-blisters, and to centimeter-scale laminated beam specimens. The pressurized micro-blisters offer a tunable approach for strain engineering in potential quantum technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
该奖项将开发理论和计算模型,以及实验方法,以促进对多层范德华材料和异质结构机制的基本理解。这些材料和结构具有有希望的应用,例如新型探测器,传感器和量子发射器。范德华材料被认为是一类重要的量子材料,对于即将到来的第二量子革命(量子2.0)至关重要。人们已经认识到,范德华材料中的应变的存在可以深刻影响其电子和光学特性,并且该应变可用于调整其物理特性,从而为力学提供了机会。为了实现这些应用,必须了解各种类型的二维材料与管理应变分布的力学之间的范德华相互作用。如果成功,这项研究将使材料研究的机制发展到第二量子革命的最前沿,从而通过控制和操纵单个量子系统来开辟新的机会。 The project will provide excellent research and education opportunities for graduate and undergraduate students, and promote diversity by recruiting and mentoring students from underrepresented groups.The objectives of the research include: (i) The development of a theoretical framework for the mechanics of multilayered van der Waals (vdW) materials, based on atomistically informed potential energy functions for the vdW interactions between 2D materials, coupling adhesive normal interactions with periodic剪切相互作用; (ii)开发了扭曲和紧张的双层VDW材料的计算模型,包括带有不均匀变形的加压微型泡; (iii)开发多尺度实验方法,以表征各种2D材料之间的VDW相互作用。该研究的智力优点源于理论和计算建模与新实验的整合,以研究多层VDW材料和异质结构的机制。多尺度建模方法补充了基于第一原理的原子模型,并且具有扩展大型系统的优势。相应地,将开发多尺度实验,从纳米容器到微型爆炸,再到厘米尺寸的层压梁样品。加压的微型布莱斯特为潜在量子技术提供了一种可调节的方法。该奖项反映了NSF的法定任务,并且使用基金会的知识分子优点和更广泛的影响评估标准,被认为值得通过评估来获得支持。
