The goal of this proposal is to investigate alternative carbon-based materials that can be processed at low cost and that can more efficiently convert light into electricity. The roadblock to developing such materials is our lack of understanding. In this project recently invented scanned probe microscopes will be used to create images of electrons moving in plastic circuits and in solar cells. The information will be used to guide synthetic chemists to make improved materials. State-of-the-art variable-temperature vacuum electric force microscopy will be used to probe charge injection and trapping in organic electronic devices, and the local charge mobility in an organic thin-film device will be imaged via a new scanned probe technique that detects local electric field fluctuations. The results will broadly impact our thinking about organic electronic materials, with application to light emitting diodes and organic solar cell technology. This project represents a unique opportunity to train graduate students in the arts of advanced scanned probe microscopy and nanofabrication, two skills that appear to be in ever-increasing demand. In order to assure the broadest possible interdisciplinary training in materials research, students on this project will work on collaborative summer projects with scientists at federal and industrial laboratories.%%%The goal of this proposal is to help discover and invent new materials for making more efficient solar cells and more cost effective plastic circuits. Inventing improved solar cells is crucial because our country needs to develop better, more renewable sources of energy. If plastic circuits could be developed it would lead to new methods of high interest to industry, e.g., for tracking products and interfacing with medical sensors. Existing materials are simply not up to these tasks. Students trained in this area will be highly competitive in the job market.

该提案的目的是研究可以低成本处理的替代碳基材料，并且可以更有效地将光转换为电力。 开发这种材料的障碍是我们缺乏理解。 在该项目中，最近发明的扫描探针显微镜将用于创建在塑料电路和太阳能电池中移动的电子图像。 该信息将用于指导合成化学家进行改进的材料。最先进的变量真空电力显微镜将用于探测有机电子设备中的电荷注入和捕获，并且将通过一种新的扫描探针技术来对有机薄膜设备中的局部电荷迁移率进行成像，以检测局部电场电场波动。 结果将广泛影响我们对有机电子材料的思考，并应用发射二极管和有机太阳能电池技术。 该项目是一个独特的机会，可以培训高级扫描探针显微镜和纳米制作的艺术研究生，这两种技能似乎在不断增加的需求中。 为了确保在材料研究中进行最广泛的跨学科培训，该项目的学生将与联邦和工业实验室的科学家进行合作夏季项目。%%％该提案的目标是帮助发现和发明新的材料，以制造更有效的太阳能电池和更具成本成本的有效塑料循环。 发明改进的太阳能电池至关重要，因为我们国家需要更好地发展能够提供更好的能源。 如果可以开发塑料电路，它将导致工业兴趣高的新方法，例如跟踪产品并与医疗传感器进行接口。 现有材料根本不符合这些任务。 在该领域培训的学生将在就业市场上具有很高的竞争力。
