Objectives: The proposed research will create electronic and optoelectronic systems that can be reversibly stretched or compressed to large strains, while providing strain-independent electrical performance at the level of state-of-the-art devices built on brittle semiconductor wafers. These systems will exploit inorganic semiconductor nanomaterials configured into structural shapes that can geometrically accommodate large mechanical deformations without imparting significant strains in the materials themselves. Comprehensive theoretical models will provide a basic understanding of the physics of these systems, and guide design of systems capable of eliminating the influence of mechanical strains on device performance.Intellectual Merit: The scientific and engineering thrusts include: 1) Semiconductor nanomaterials to build high quality electronic and optoelectronic devices on substrates other than semiconductor wafers. These materials will be integrated with ultrathin polymer sheets using transfer printing techniques. 2) Elastomeric transfer elements and substrates to transform these nanomaterials and devices from their initial planar configurations into various buckled, curvilinear and "wavy" shapes needed to achieve stretchable/compressible mechanical response. 3) Analytical and computational models to understand the physics associated with strain-induced deformations in these nanomaterials. Broader Impact: Successful development of the proposed approaches will create entirely new classes of electronic and optoelectronic systems, with wide-ranging application possibilities. The broad appeal of these systems provides excellent educational opportunities not only for graduate and undergraduate students, but also for the wider community interested in new technology. Interactive displays at science/technology museums will form a focus of outreach activities.

目的：拟议的研究将创建电子和光电系统，可以可逆地拉伸或压缩到大应变，同时在脆性半导体晶片上构建的最先进器件水平上提供应变无关的电气性能。 这些系统将利用无机半导体纳米材料配置成结构形状，可以在几何上适应大的机械变形，而不会在材料本身中产生显著的应变。 全面的理论模型将提供对这些系统物理学的基本了解，并指导能够消除机械应变对器件性能影响的系统设计。智力优势：科学和工程重点包括：1）半导体纳米材料用于构建高质量的电子和光电子器件在半导体晶片以外的衬底上。 这些材料将使用转移印刷技术与可固化聚合物片材集成。2)弹性体转移元件和基底，以将这些纳米材料和器件从其初始平面构型转变成实现可拉伸/可压缩机械响应所需的各种弯曲、曲线和“波浪”形状。3)分析和计算模型，以了解与这些纳米材料中的应变诱导变形相关的物理学。 更广泛的影响：所提出的方法的成功开发将创造全新的电子和光电系统，具有广泛的应用可能性。 这些系统的广泛吸引力不仅为研究生和本科生提供了极好的教育机会，而且还为对新技术感兴趣的更广泛的社区提供了良好的教育机会。 科技博物馆的互动展览将成为推广活动的重点。
