On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

Advanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Unprecedented Wall‐Atomically Thick Bi5O7Br Nanotubes Embedding Abundant Bi Nanodots Boosting Efficiently Photothermal Coupling Catalytic CO2 Conversion

EcoEnergy, EarlyView.
Atomically thin Bi5O7Br nanotubes embedded with abundant Bi nanodots were constructed as an efficient photothermal catalyst for CO2 conversion. The localized surface plasmon resonance and photothermal effect of Bi nanodots synergistically enhance light harvesting, charge utilization, and reaction kinetics, resulting in significantly improved CO2 to CO ...
