The objective of this research is to develop strategies for materials integration based upon the ion-cut-synthesis process, which consists of simultaneous synthesis and layer transfer of electrically-active nanostructures. This research objective will be accomplished by developing an improved understanding of the nanostructure and bubble formation processes. In addition, the substrate bonding and thermal processing steps will be optimized for a variety of bonding agents, substrate materials, and ion-cut methods. This project will lay the foundation for a larger effort for developing integration methods for a variety of important technologies. A major technological hurdle to global energy sustainability is the replacement of environmentally harmful and rapidly depleting energy sources with ecologically responsible and renewable sources. Solar power is one promising avenue to clean energy; however, the relative efficiency, availability, or cost of solar power as compared to polluting power sources such as fossil fuels can preclude its widespread application. In terms of efficiency of solar cells and solar concentrators, the majority of energy (up to 95%) is converted to waste heat. The pairing of thermoelectric devices with solar cells and/or solar concentrators is a promising route to recovery of otherwise wasted energy. To this end, this project involves study of nanostructured materials for efficient conversion of both light and heat from the sun to electricity, as well as the development of a thin-film layer transfer technique to reduce materials cost. Thus, if successful, the ion-cut-synthesis approach would enable efficient conversion of both heat and light to electricity, providing a possible solution to the challenge of cost-efficient energy sustainability.

本研究的目的是开发基于离子切割合成工艺的材料集成策略，该工艺包括电活性纳米结构的同时合成和层转移。这一研究目标将通过发展一个更好的理解的纳米结构和气泡的形成过程。 此外，基板粘合和热处理步骤将针对各种粘合剂、基板材料和离子切割方法进行优化。 该项目将为开发各种重要技术的集成方法奠定基础。全球能源可持续性的一个主要技术障碍是以对生态负责的可再生能源取代对环境有害和迅速枯竭的能源。 太阳能是清洁能源的一种有前途的途径;然而，与污染性能源如化石燃料相比，太阳能的相对效率、可用性或成本可能妨碍其广泛应用。就太阳能电池和太阳能集中器的效率而言，大部分能量（高达95%）被转化为废热。热电装置与太阳能电池和/或太阳能集中器的配对是回收否则浪费的能量的有希望的途径。为此，该项目涉及研究纳米结构材料，以有效地将太阳的光和热转化为电，以及开发薄膜层转移技术，以降低材料成本。 因此，如果成功，离子切割合成方法将能够有效地将热和光转化为电，为具有成本效益的能源可持续性挑战提供可能的解决方案。
