#1510934Filler, Michael A.The principal investigator proposes a new type of material for not only capturing radiation energy such as that from the Sun but also manipulating the direction of the energy flow. The research effort combines experiment and theory, and will test the hypothesis for harvesting energy from mid-infrared light. The education effort will include (1) K-12 and undergraduate STEM education, with an emphasis on underrepresented minorities and (2) Georgia Tech summer camp activity entitled "Wearing the Sun," where Atlanta area high school students learn about solar energy harvesting by creating personalized, sunlight-activated clothing (i.e., T-shirts, etc.), will be enhanced during the proposed project. The proposal aims to investigate the mid-infrared localized surface plasmon resonances (LSPRs) supported in selectively doped Si nanowires by understanding the structural and synthetic parameters that influence LSPR quality factor and probing the near-field coupling of neighboring LSPRs. It also seeks to demonstrate enhanced vibrational mode sensing in thermal radiation hot spots. By coupling experiment and theory, the PI will test the hypothesis that mid-infrared light can be confined via doped-Si resonators to the same extent as visible/near-infrared light in conventional plasmonic materials. The proposed efforts will develop vapor-liquid-solid nanowire growth to engineer extreme light localization and transport via precise control of resonator geometry, carrier density, and spacing, hoping to develop ultra-compact thermal radiation waveguides, modulators, and detectors.

#1510934Filler，Michael A.首席研究员提出了一种新型材料，不仅可以捕获来自太阳的辐射能量，还可以操纵能量流的方向。 这项研究结合了实验和理论，并将测试从中红外光中获取能量的假设。 教育工作将包括（1）K-12和本科STEM教育，重点是代表性不足的少数民族和（2）格鲁吉亚技术夏令营活动，题为“穿着太阳”，亚特兰大地区的高中学生通过创建个性化的，阳光激活的衣服（即，T恤等），将在拟议项目中得到加强。 该提案的目的是研究中红外局域表面等离子体共振（LSPR）支持选择性掺杂的硅纳米线的结构和合成参数，影响LSPR的品质因数和探测附近的LSPR的近场耦合。 它还试图证明在热辐射热点增强振动模式传感。 通过耦合实验和理论，PI将测试中红外光可以通过掺杂Si谐振器限制到与传统等离子体材料中的可见光/近红外光相同的程度的假设。 拟议的工作将开发气液固纳米线生长，通过精确控制谐振器几何形状、载流子密度和间距来设计极端的光定位和传输，希望开发超紧凑的热辐射波导、调制器和检测器。
