Engineering Exciton g‐Factors With Light in Type‐II Heterostructures
All‐optical approaches have emerged as cutting‐edge alternatives for ultrafast, energy‐efficient, and spatially localized tuning and switching of material properties. In our work, we demonstrate how light intensity alone can be leveraged to engineer g‐factors from a single‐type of carrier in type‐II heterostructures through Coulomb‐induced wavefunction

Phonon Polariton Confinement in Isotopically Pure MOVPE‐Grown BN Triangles
Phonon polaritons are confined in MOVPE‐grown isotopically pure 10BN$^{10}{\rm BN}$ triangles. The resonator modes are excited and mapped by near‐field spectroscopy. Through scanning a wide infrared frequency range and modeling, the polariton dispersion relation is retrieved.

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.

1D and 3D nanoporous anodic aluminum oxide (AAO) surfaces were functionalized with stearic acid (STA) to increase hydrophobicity and reduce the influence of humidity on radiative cooling performance. The STA coating improves cooling behavior under humid atmospheric conditions (Madrid summer), before while keeping the optical properties required for ...
