Harvesting the loss: surface plasmon-based hot electron photodetection
Although the nonradiative decay of surface plasmons was once thought to be only a parasitic process within the plasmonic and metamaterial communities, hot carriers generated from nonradiative plasmon decay offer new opportunities for harnessing absorption loss. Hot carriers can be harnessed for applications ranging from chemical catalysis, photothermal heating, photovoltaics, and photodetection...
متن کاملHot-electron nanoscopy using adiabatic compression of surface plasmons.
Surface plasmon polaritons are a central concept in nanoplasmonics and have been exploited to develop ultrasensitive chemical detection platforms, as well as imaging and spectroscopic techniques at the nanoscale. Surface plasmons can decay to form highly energetic (or hot) electrons in a process that is usually thought to be parasitic for applications, because it limits the lifetime and propaga...
متن کاملHot Electrons and Hot Plasmons for Photovoltaics
Hot Electrons and Hot Plasmons for Photovoltaics David J. Norris Optical Materials Engineering Laboratory, ETH Zürich We will discuss two recently observed phenomena with implications for photovoltaic devices. First, it is well known that conventional silicon solar cells lose a significant fraction of their absorbed energy when electrons that are excited high into the conduction band cool to th...
متن کاملStrong and highly asymmetrical optical absorption in conformal metal-semiconductor-metal grating system for plasmonic hot-electron photodetection application
We propose an architecture of conformal metal-semiconductor-metal (MSM) device for hot-electron photodetection by asymmetrical alignment of the semiconductor barrier relative to the Fermi level of metals and strong energy localization through plasmonic resonances. Compared with the conventional grating design, the multi-layered grating system under conformal configuration is demonstrated to pos...
متن کاملObservation of a hybrid state of Tamm plasmons and microcavity exciton polaritons
We present evidence for the existence of a hybrid state of Tamm plasmons and microcavity exciton polaritons in a II-VI material based microcavity sample covered with an Ag metal layer. The bare cavity mode shows a characteristic anticrossing with the Tamm-plasmon mode, when microreflectivity measurements are performed for different detunings between the Tamm plasmon and the cavity mode. When th...
