Strong Coupling in all‐Polymer Planar Microcavities

open access: yesAdvanced Optical Materials, EarlyView.
Strong Coupling has been achieved in an all‐polymer microcavity with dielectric contrast Δn = 0.33 doped with TDBC. A Rabi splitting of 39 meV has been measured opening novel perspectives for polymer photonics. ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into ...

Nanoporous Scaffold‐Assisted Ligand‐Free CsPbBr3 Quantum Dots for Bright and Ultrapure Green Light‐Emitting Diodes

open access: yesAdvanced Optical Materials, EarlyView.
Networks of confined CsPbBr3 perovskite quantum dots, synthesised within nanoporous silica scaffolds using precursors containing different combinations of butylammonium bromide and crown ether additives, enable electroluminescent devices with 400‐fold enhanced charge injection and transport with respect to control devices, yielding ultrapure green ...

Strong Photoluminescence Enhancement in All‐Dielectric Ge Thin Film Metasurfaces for Integration on the Si Platform

open access: yesAdvanced Optical Materials, EarlyView.
Germanium (Ge) all‐dielectric metasurfaces can be leveraged to strongly enhance the radiative emission from Ge layers grown on silicon‐on‐insulator substrates by industry‐standard processes. At room‐temperature, the narrowband photoluminescence (PL) intensity is enhanced by a factor ∼40× with respect to unstructured films.

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes

open access: yesAdvanced Optical Materials, EarlyView.
Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

open access: yesAdvanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (

A Perspective on Interactive Theorem Provers in Physics

open access: yesAdvanced Science, EarlyView.
Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics
