Graphical Abstract

Thumbnail image of graphical abstract

The generation and conduction of photoelectrons in ligated metallic Au NPs are demonstrated, and their key factors include tunneling of photoexcited electrons, the close packing of the NP network, and increased photoelectron-to-intrinsic electron ratio associated with ligand passivation. In view of their inherent characteristics, metallic NPs may provide a promising alternative to semiconductors in photocurrent and photodetection applications.
