Nanocrystal-based Optoelectronic Devices

ORAL

Abstract

Optoelectronic devices capable of detecting and emitting light on a scale well below its wavelength could have a profound impact on basic and applied experimental research in light-based electronics, on-demand photon generation, and for studying poorly understood quantum phenomena such as blinking and spectral wandering. We present a fabrication procedure for ultrasmall, nanocrystal optoelectronic devices based on self-assembled layers of quantum dots in plasmonically-active gold nanogaps. We provide preliminary experimental results which examine the possibility for surfaced-enhanced fluorescence, subwavelength detection and emission of light as well as plasmon-based optical trapping in these systems.
