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.

目标：拟议的研究将创建可以可逆拉伸或压缩至大应变的电子和光电系统，同时提供与建立在脆性半导体晶圆上的最先进设备水平的应变无关的电气性能。 这些系统将利用配置成结构形状的无机半导体纳米材料，这些结构形状可以在几何上适应大的机械变形，而不会给材料本身带来显着的应变。 综合理论模型将提供对这些系统的物理原理的基本理解，并指导能够消除机械应变对器件性能影响的系统设计。智力优点：科学和工程的推动力包括：1）构建高质量的半导体纳米材料半导体晶圆以外的基板上的电子和光电器件。 这些材料将使用转移印刷技术与超薄聚合物片材集成。 2) 弹性体转移元件和基底，用于将这些纳米材料和装置从其最初的平面配置转变为实现可拉伸/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应变引起的变形相关的物理原理。 更广泛的影响：所提出的方法的成功开发将创建全新类别的电子和光电系统，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，而且为对新技术感兴趣的更广泛的社区提供了极好的教育机会。 科学/技术博物馆的互动展示将成为外展活动的重点。
