An optical antenna-diode for photodetection. (A) Band diagram for plasmonically driven internal photoemission ... with a spectral response extending to energies well below the semiconductor band edge.

In combination, these strategies allow spectral photodetection coverage from the ultraviolet to the near-infrared. MHPs, on the other hand, are hybrid organic–inorganic compounds with the basic ...

First, the terminology and basic physical mechanisms of photodetection are discussed, then the experimental realizations of various kinds of photodetector, including techniques to enhance ...
