0101794卡特液体可处理固态半导体显示了极大地改变未来技术的承诺，通过提供改进的和新的设备功能，大大降低能源，环境和处理成本比传统处理半导体。在用于光电子应用的液体可加工材料类别中，基于聚合物的半导体提供了一些最高的电荷载流子复合和产生效率，以及高度可调、柔性、重量轻和可掺杂的优点。尽管如此，由于在环境条件下难以实现向聚合物中的有效电荷注入和具有长器件寿命的高电流密度，因此制造高性能聚合物基器件存在重大挑战。最近的工作，多层和共混的聚合物为基础的结构，含有电荷传输层已着手克服这些限制。虽然这一方向是有前途的，但它也带来了新的挑战，即我们如何理解聚合物基器件的多层异质结构中的电荷注入、输运、产生和复合？本提案的目的是通过多组分聚合物基发光二极管和光致发光器件的系统实验和模拟来解决这个问题。为了实现这一目标，他们汇集了来自学术，工业和政府实验室的三位科学家组成的跨学科团队。苏·卡特是加州大学的物理学教授，是聚合物光电器件电学和光学特性方面的专家。J.坎贝尔斯科特是IBM Almaden研究中心的研究人员，是有机发光器件设计、表征和模拟方面的专家。最后，国家可再生能源实验室的首席科学家大卫金利是光伏技术和无机半导体纳米颗粒合成方面的专家。这种广泛的经验，加上他们对学生教育和这些领域的进步的承诺，应该使他们能够实现他们的目标，对他们对多层聚合物光电器件的理解产生重大影响，增加他们的科学创新和技术可行性的潜力。

0101794CarterLiquid processable solid state semiconductors show promise of dramatically changing futuretechnologies by offering improved and new device functionality at significantly lower energy, environmental and processing costs than traditionally processed semiconductors. In the class of liquid processable materials for optoelectronic applications, polymer-based semiconductors offer some of the highest charge carrier recombination and generation efficiencies combined with advantages of being highly tunable, flexible, light weight and dopable. Nonetheless, significant challenges exist for making high performance polymer-base devices due to difficulties in achieving both efficient charge injection into the polymer and high current densities with long device lifetimes under ambient conditions. Recent work on multilayered and blended polymer-based structures that contain charge-transport layers has been undertaken to overcome these limitations. While this direction is promising, it has also introduced a new challenge, namely how do we understand charge injection, transport, generation and recombination in multilayered heterostructures of polymer-baseddevices?The objective of this proposal is to address this question through systematic experiments andsimulations on multicomponent polymer-based light emitting diodes and photovoltaics. Toaccomplish this objective, they have brought together an interdisciplinary team of three scientists from academic, industrial and government labs. Sue Carter, a physics professor at the University of California, is an expert in electrical and optical characterization of polymer-based optoelectronic devices. J. Campbell Scott, a Research Staff Member at IBM Almaden Research Center, is an expert in the design, characterization and simulation of organic-based light emitting devices. Finally, David Ginley, a principle scientist at the National Renewable Energy Laboratories, is an expert in photovoltaic technologies and the synthesis of inorganic semiconducting nanoparticles. This extensive experience, combined with their demonstrated commitment to the education of students and to the advancement of these fields, should enable them to achieve their goal to have significant impact on their understanding of multilayered polymer-based optoelectronic devices, increasing their potential for scientific innovation and technological viability.
