文摘
- •
A “stereo” hot-electron device based on hyperbolic metamaterials is presented.
- •
Results show broadband and omnidirectional enhancement in external quantum efficiency.
- •
Results show great potential in energy-efficient, sub-bandgap photodetectors, spectrometers, and plasmonic sensors.
- •
Applicability of hot-electron devices to energy harvesting is evaluated.
