Photo‐Excitations in Halide Perovskites: Where Do Simulations and Experiments Meet?

Laser &Photonics Reviews, EarlyView.
Aiming to bridge the gap between simulations and measurements of light–matter couplings and photo‐excitations in new functional materials, this perspective highlights insights and bottlenecks of state‐of‐the‐art experimental and theoretical methods (2D electronic spectroscopy vs.

Micro‐Transfer Printed Continuous‐Wave and Mode‐Locked Laser Integration at 800 nm on a Silicon Nitride Platform

Laser &Photonics Reviews, EarlyView.
A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Ultralow‐Backscattering Induced Mode Splitting in Chipscale Valley Photonic Topological Cavities

Laser &Photonics Reviews, EarlyView.
The proposed in‐situ metrology based on mode splitting quantifies the ultralow backscattering of topological valley edge states at a single sharp corner, demonstrating near‐lossless topological transport (0.09 dB/corner) on a silicon chip. This work provides insight into the robustness of the photonic valley system and shows the great potential of ...

Squaring the Magic

, 2012
We construct and classify all possible Magic Squares (MS's) related to Euclidean or Lorentzian rank-3 simple Jordan algebras, both on normed division algebras and split composition algebras.

Water Co‐Adsorption in Ultrathin Films of Ionic Liquids on Pt(111)

ChemistryOpen, EarlyView.
At 100 K, IL adsorption on D2O precovered Pt(111) partially displaces interfacial water resulting in a water‐IL co‐adsorbed layer. Upon heating to 130 K, IL ions migrate to the metal interface, thereby destabilizing adsorbed water as shown by the ≈10 K reduction in its desorption temperature.

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

Small, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.

Low Temperature MOCVD Synthesis of High‐Mobility 2D InSe

Small, EarlyView.
We report on the low‐temperature, wafer‐scale metal‐organic chemical vapor deposition (MOCVD) growth of phase‐pure two‐dimensional indium selenide (InSe). By adjusting the Se/In ratio and temperature, we mapped In‐rich to Se‐rich InxSey phase space and identified the conditions that produce epitaxial, layered InSe. Structural and spectroscopic analyses

Accelerated Catalyst Development via Kinetically Controlled Solid‐State Laser Synthesis and Automated Electrochemical Screening

Small, EarlyView.
A rapid laser‐based method produces metal nanoparticles on carbon under ambient conditions, eliminating the need for solvents and surfactants. By adjusting laser parameters, particle size and uniformity are precisely controlled and rapidly analyzed using X‐ray diffraction.
