Three‐dimensional hybrid perovskite heterostructure single crystals toward highly efficient x‐ray detectors

InfoMat, EarlyView.
This study presents for the first time a self‐assembled three‐dimensional perovskite heterojunction single crystal with organic cations and Pb coordination, (MHy)2Pb(2)Cl4·Pb(1)Cl2 (MPC). The MPC possesses carriers with different conformations and undergoes an ordered–ordered structural transition as the temperature increases, which ultimately realizes

Intensity Noise Dynamics in Terahertz Quantum Cascade Lasers

Laser &Photonics Reviews, EarlyView.
Intensity‐noise dynamics in terahertz quantum cascade lasers are investigated across single‐mode, dense‐comb and harmonic‐comb regimes using graphene thermoelectric detectors. Harmonic combs show ∼10% lower relative intensity noise, while RIN scales as P0−γ$P_0^{ - \gamma }$ with γ≈1.2$\gamma \approx 1.2$, revealing a crossover from spontaneous ...

Carbon dots in photocatalytic water splitting and related proton/electron‐coupled reactions: Multiscale regulation of charge dynamics and interfacial processes

Responsive Materials, EarlyView.
This review summarizes CD‐based photocatalytic water splitting as a multiscale charge‐utilization process, linking photoexcitation, charge separation, interfacial transfer, charge storage, and catalytic consumption. It highlights how CD structures and interfaces regulate charge pathways and reaction microenvironments, and how advanced characterization,
