Photoresponsivity of silver nanoparticles decorated graphene–silicon Schottky junction

Abstract

We demonstrate formation of the silver nanoparticles (Ag-NPs) in chemical vapor deposited graphene by dissolving base Ag foil and their integration for Schottky junction photodetector fabrication.

Carbon/Silicon Heterojunction Solar Cells: State of the Art and Prospects

“…As discussed above, a tunable work function of the graphene could afford the opportunity of efficient carrier injection in graphene/Si solar cells. An effective way to modify the work function of graphene by p‐type chemical doping, such as acids, polymers, Au, Ag, boron, ionic liquid electrolytes, and so on, could lead to the performance improvement of solar cells. Chemical doping will increase not only the conductivity of graphene but also the built‐in field at the interface of graphene/Si.…”

Investigating photoresponsivity of graphene-silver hybrid nanomaterials in the ultraviolet

“…Various schemes to enhance the interaction of light with graphene [2][3][4][5][6] have been implemented, of which integration with plasmonic nanoparticles is particularly attractive. [7][8][9][10] The subwavelength localization and enhancement of the electric field around the nanoparticles can lead to a higher responsivity at the plasmon resonance. They also offer tunability in terms of spectral response, e.g., by changing the shape, size, and material, or polarizationresponse, e.g., by changing the aspect ratio.…”

Cation exchange assisted low temperature chemical synthesis of ZnO@Ag2S core–shell nanoparticles and their photo-catalytic properties

“…Semiconductors nanoparticles (NPs), and because of their outstanding optical properties are considered as promising materials [1] for different applications such as solar cells [2], photodetectors [3], and light-emitting diodes [4]. Zinc oxide (ZnO) NPs as a cheap semiconductor with a wide direct band gap (3.37 eV) at room temperature [5] showed a potential for the use as photocatalyst [6], photodetectors [7], gas sensors [8], piezoelectric sensors [9] and ultraviolet laser [10].…”
