    • An electrically driven device for surface enhanced Raman spectroscopy includes a first electrode, a substrate positioned proximate to the first electrode, a plurality of cone shaped protrusions formed integrally with or on a substrate surface, a Raman signal-enhancing material coated on each protrusion, and a second electrode positioned relative to the first electrode at a predetermined distance. Each of the protrusions has a tip with a radius of curvature ranging from about 0.1 nm to about 100 nm. The second electrode is positioned relative to the first electrode such that the electrodes together produce an electric field when a voltage bias is applied therebetween. The electric field has a field distribution that creates a stronger field gradient at a region proximate to the tips than at other portions of the substrate.
    • 用于表面增强拉曼光谱的电驱动装置包括第一电极,靠近第一电极定位的基板,与基底表面一体地形成的多个锥形突起,涂覆在每个突起上的拉曼信号增强材料,以及 相对于第一电极以预定距离定位的第二电极。 每个突起具有具有约0.1nm至约100nm范围的曲率半径的尖端。 第二电极相对于第一电极定位,使得当在其之间施加电压偏置时,电极一起产生电场。 电场具有场分布,其在靠近尖端的区域处产生比在衬底的其它部分更强的场梯度。

    • A nanowire-based photonic device and an array employ nanowires connecting between coaxially arranged electrodes in a non-uniform manner along a vertical extent of the electrodes. The device includes a pair of the electrodes separated by a circumferential gap. The nanowires chaotically emanate from an inner electrode of the pair and connect across the circumferential gap to an outer electrode of the pair. The array includes an outer electrode having an interconnected pattern of cells and inner electrodes, one per cell, arranged coaxially with and separated from the outer electrode by respective circumferential gaps. The nanowires chaotically emanate from the inner electrodes and connect across the respective circumferential gaps of the cells to the outer electrode. The device and the arrays further include a semiconductor junction between the electrodes.
