Open AccessReal-space imaging of acoustic plasmons in large-area graphene grown by chemical vapor deposition
An acoustic plasmon mode in a graphene-dielectric-metal structure has recently been spotlighted as a superior platform for strong light-matter interaction. It originates from the coupling of graphene plasmon w...

Open AccessObservation of Wavelength-Dependent Quantum Plasmon Tunneling with Varying the Thickness of Graphene Spacer
Plasmonic coupling provides a highly localized electromagnetic field in the gap of noble metals when illuminated by a light. The plasmonic field enhancement is generally known to be inversely proportional to t...

Open AccessTrapped charge-driven degradation of perovskite solar cells
Perovskite solar cells have shown unprecedent performance increase up to 22% efficiency. However, their photovoltaic performance has shown fast deterioration under light illumination in the presence of humid a...

Open AccessElectronically tunable extraordinary optical transmission in graphene plasmonic ribbons coupled to subwavelength metallic slit arrays
Subwavelength metallic slit arrays have been shown to exhibit extraordinary optical transmission, whereby tunnelling surface plasmonic waves constructively interfere to create large forward light propagation. ...

Electronic modulation of infrared radiation in graphene plasmonic resonators
All matter at finite temperatures emits electromagnetic radiation due to the thermally induced motion of particles and quasiparticles. Dynamic control of this radiation could enable the design of novel infrare...
