Much progress has been made in the synthesis and characterization of a variety of nanoscale materials with varying size, shape and composition. However, a significant bottleneck exists in applications due to the lack of reliable and cost-effective means of patterning or assembling nanoscale materials into structures suitable for devices and functional systems. The program proposed here aims to develop hybrid materials that can facilitate processing of nanocrystals especially to make them compatible with readily available microfabrication techniques. The hybrid materials considered here will consist of inorganic nanocrystals encapsulated in monodisperse polymer colloids. This combination provides an attractive opportunity to merge unique properties of nanoscale materials with the processibility of polymers opening up numerous possibilities in fabrication and manufacturing of devices and systems containing tunable nanostructures. Compatibility with readily available microfabrication processes to build organized nanocrystal arrays will be examined.Hybrid building blocks considered here can integrate nanoscale materials into currently employed top-down approaches to fabrication and processing, potentially expediting the realization of numerous applications in areas such as electronics and photonics. The multidisciplinary approach including chemical synthesis, microfabrication, microscopy and optical and electrical characterization is central to this research and provides an important educational component. Multifaceted challenges to be tackled here will provide ample educational opportunities needed for researchers in emerging cross-disciplinary fields. Diverse topics on nanoscale materials to be explored in this research program will also serve as a basis for several topics for undergraduate and graduate courses.

在各种尺寸，形状和组成不同的纳米级材料的合成和表征中取得了很多进展。 但是，由于缺乏将纳米级材料构图或组装成适合设备和功能系统的结构，因此在应用中存在着重要的瓶颈。 此处提出的计划旨在开发可以促进纳米晶体处理的混合材料，尤其是使其与容易获得的微加工技术兼容。 此处考虑的杂种材料将由封装在单分散聚合物胶体中的无机纳米晶体组成。 这种组合提供了一个有吸引力的机会，可以将纳米级材料的独特特性与聚合物的处理性相结合，从而在制造和制造含有可调纳米结构的设备和系统中开放了许多可能性。 将检查与随时可用的微观加工过程的兼容性，以构建有组织的纳米晶体阵列。此处考虑的杂化构件可以将纳米级材料集成到当前采用的自上而下的制造和加工方法中，并有可能加快在电子和光电素等领域中实现众多应用。 多学科方法，包括化学合成，微分化，显微镜以及光学和电特性，这对于这项研究至关重要，并提供了重要的教育成分。 这里要解决的多方面挑战将为新兴的跨学科领域的研究人员提供充足的教育机会。 在本研究计划中探索的纳米级材料的各种主题也将作为本科和研究生课程的几个主题的基础。
