Plasmon–Exciton Coupling Enhances Second‐Order Nonlinear Response in Borophene–ZnO Hybrid Structures

Laser &Photonics Reviews, EarlyView.
Nonlinear interactions between plasmons in borophene and excitons in ZnO lead to enhanced nonlinear and incoherent cathodoluminescence, as well as coherent second harmonic generation, under electron‐beam and laser irradiations, respectively. The anisotropic response of borophene, revealed as in‐plane hyperbolic polariton propagation, acts as a control ...

Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching

Laser &Photonics Reviews, EarlyView.
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

Room‐Temperature Polariton Condensation Into Superscar Modes in Growth‐Defined Triangular Micro‐Prism Resonators

Laser &Photonics Reviews, EarlyView.
High‐Q superscar modes in growth‐defined triangular GaN micro‐prism resonators enable strong exciton–photon coupling and room‐temperature polariton condensation, offering a scalable platform for integrated III‐nitride polariton devices. ABSTRACT Group III‐nitride semiconductors are regarded as key materials for realizing polariton devices operating at ...

New Insights About the Role of Sn‐Rich and Pb‐Rich Phases Over the Corrosion Mechanism of Low‐Tin Quaternary Bronze Alloys Under Sulfur‐Containing Conditions

Materials and Corrosion, EarlyView.
A mechanistic proposal for the initial steps of quaternary bronze corrosion in media containing sulfate was described. The process is driven by microgalvanic effects along the microstructure, generating anodic sites over lead and tin rich phases and cathodic sites onto Cu‐rich phases.

Corrosion of Potential Canister Materials During Oxic to Anoxic Transient in Compacted Bentonite

Materials and Corrosion, EarlyView.
A comprehensive analytical approach was applied to investigate material degradation phenomena of cast iron and copper as potential canister materials for the safe disposal of high‐level radioactive waste, as well as compacted bentonite exposed to artificial water relevant for disposal. ABSTRACT The long‐term performance of the engineered barrier system
