Half-metallic carbon nitride nanosheets with micro grid mode resonance structure for efficient photocatalytic hydrogen evolution

open access: yesNature Communications, 2018
The “storage” of sunlight as a chemical fuel can provide renewable on-demand energy, although current earth-abundant materials usually show low activities.

Photoinduced semiconductor-metal transition in ultrathin troilite FeS nanosheets to trigger efficient hydrogen evolution

open access: yesNature Communications, 2019
While earth-abundant materials are promising catalysts for renewable energy conversion, such materials tend to display poor activities. Here, authors show FeS troilite nanosheets to undergo a near-infrared light-triggered transition to a phase that ...

Q-factor enhancement of Fano resonance in all-dielectric metasurfaces by modulating meta-atom interactions

open access: yesScientific Reports, 2017
We numerically investigated the effects of meta-atom interactions on the Fano resonance in all-dielectric metasurfaces by introducing alternately flipped asymmetric paired bars (APBs) and split asymmetric paired bars (SAPBs).
