等离子体纳米间隙中的光伏和热电子

Photovoltages and hot electrons in plasmonic nanogaps

Douglas Natelson, Charlotte I. Evans, Pavlo Zolotavin

摘要:

在照射下的金属纳米结构中,多个不同的过程可以驱动电流流动,并且在开路配置中,这些过程中的一些导致开路光电压的产生。在照射波长处具有等离子体共振的结构可以具有增强的光电压响应,这是由于与入射辐射场的增加的相互作用以及通过等离子体激发本身的动力学而成为可能的过程。在这里,我们回顾了连续金属纳米线的热电效应驱动的光电压响应和热电子产生和隧穿驱动的光电压响应。我们讨论了通过局部等离子体共振和传播表面等离子体激元的组合,提高和量化热电子产生和响应的前景。

英文摘要:

In metal nanostructures under illumination, multiple different processes can drive current flow, and in an open- circuit configuration some of these processes lead to the production of open-circuit photovoltages. Structures that have plasmonic resonances at the illumination wavelength can have enhanced photovoltage response, due to both increased interactions with the incident radiation field, and processes made possible through the dynamics of the plasmon excitations themselves. Here we review photovoltage response driven by thermoelectric effects in continuous metal nanowires and photovoltage response driven by hot electron production and tunneling. We discuss the prospects for enhancing and quantifying hot electron generation and response via the combination of local plasmonic resonances and propagating surface plasmon polaritons.
