Energy transfer from plasmonic nanoparticles to semiconductors can expand the available spectrum of solar energy-harvesting devices. Here, we spatially and spectrally resolve the interaction between single Ag nanocubes with insulating and semiconducting substrates using electron energy-loss spectroscopy, electrodynamics simulations, and extended plasmon hybridization theory. Our results illustrate a new way to characterize plasmon-semiconductor energy transfer at the nanoscale and bear impact upon the design of next-generation solar energy-harvesting devices.
等离子体纳米粒子向半导体的能量转移可以扩展太阳能收集设备的可用光谱。在这里，我们使用电子能量损失光谱学、电动力学模拟和扩展等离子体杂化理论，空间和光谱分辨了单个 Ag 纳米立方体与绝缘和半导体衬底之间的相互作用。我们的结果说明了在纳米尺度上表征等离子体-半导体能量转移的新方法，并对下一代太阳能收集设备的设计产生了影响。
