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先前已经根据CNT的量子计算领域所需的需要，在碳纳米管（CNT）的光学现象（CNT）的量子机械建模方面发展了强大的技能。在这项工作中，他计划将这些技能应用于具有更广泛含义的两个建模任务：（1）从微波炉和Terahertz频率的环境辐射中提取能量； （2）通过刺激辐射的刺激排放的表面等离子体扩增 - 一种“等离子的激光”。智力优点：这项工作将填补我们对能量清除可能可能发生的事情的非常重要的孔。波波维奇小组的一份经典论文计算得出，使用螺旋直立性可以提取多达20％的环境无序微波辐射能量的能量，但是这些计算并未考虑到相干性问题和其他量子效应，并且它们并没有真正尝试描述Terahertz频率上发生的情况，而特征尺寸较小。该PI在考虑到较小的长度尺度上实施螺旋直径的一种可能方法（CNT复合结构）具有出色的核算背景。表面等离子间的新功能对于除了摩尔定律之外的NSF优先级也非常重要。广泛的影响：该项目还将对北卡罗来纳州中央大学的教育产生重大影响。 这项工作的横切和先进的性质以及PI的研究和教育整合计划，可确保此处的大量外展益处。新的能源和更快的计算机来源也可能导致。
