The PI has previously developed strong skills in quantum mechanical modeling of optical phenomena in carbon nanotubes (CNT), as required in the field of quantum computing with CNT. In this work, he plans to apply these skills to two modeling tasks with broader implications: (1) the extraction of energy from ambient radiation at microwave and terahertz frequencies ; (2) surface plasmon amplification by stimulated emission of radiation -- a "laser for plasmons."Intellectual Merit: This work will fill a very important hole in our understanding of what is possible with energy scavenging. A classic paper by Popovic's group calculated that it is possible to extract up to 20% of the energy of ambient disordered microwave radiation using spiral rectennas, but these calculations did not account for coherence issues and other quantum effects, and they did not really attempt to describe what happens at terahertz frequencies, where feature sizes are smaller. This PI has an excellent background for accounting for such effects, considering one possible way to implement spiral rectennas on smaller length scales -- CNT composite structures. New capabilities in surface plasmonics are also extremely important to the NSF priority Beyond Moore's Law. Broad Impacts: This project will also have a big impact on education at North Carolina Central University, the nation's first state-supported public liberal arts college for Afro-Americans. The cross-cutting and advanced nature of this work, and the PI's plan for integration of research and education, ensure large outreach benefits here. New sources of energy and faster computers may also result.

PI 此前已在碳纳米管 (CNT) 光学现象的量子力学建模方面积累了丰富的技能，满足 CNT 量子计算领域的需求。在这项工作中，他计划将这些技能应用于两个具有更广泛影响的建模任务：（1）从微波和太赫兹频率的环境辐射中提取能量； (2)通过受激辐射的表面等离子体激元放大——“等离子体激元激光器”。 智力优点：这项工作将填补我们对能量清除可能性的理解中的一个非常重要的空白。 Popovic小组的一篇经典论文计算出，使用螺旋整流天线可以提取高达20%的环境无序微波辐射能量，但这些计算没有考虑相干性问题和其他量子效应，他们也没有真正尝试描述在太赫兹频率下发生的情况，其中特征尺寸较小。该 PI 具有解释此类效应的良好背景，考虑了在较小长度尺度上实现螺旋整流天线的一种可能方法 - CNT 复合结构。表面等离子体激元的新功能对于国家科学基金会超越摩尔定律的优先事项也极其重要。广泛的影响：该项目还将对北卡罗来纳中央大学的教育产生重大影响，该大学是美国第一所国家支持的非裔美国人公立文理学院。 这项工作的跨领域性和先进性，以及 PI 的研究和教育一体化计划，确保了这里的巨大推广效益。新的能源和更快的计算机也可能由此产生。
