Impact of Grain Size on Low‐Temperature Carrier Phase Coherence Length in Polycrystalline Halide Perovskite Films

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Magnetoresistance measurements on a series of polycrystalline cesium tin iodide (CsSnI3) thin film devices having varying grain sizes reveal no power law dependence with clear signatures of weak anti‐localization (spin‐orbit coupling). Surprisingly, the extracted phase coherence lengths are found to be independent of grain sizes.

Self‐Catalyzed AlGaAs Nanowires and AlGaAs/GaAs Axial Heterostructures Grown by Molecular Beam Epitaxy

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 1, 7 January 2026.
Following the parameter modulation described in the manuscript, a high yield of branch‐free self‐catalyzed AlGaAs nanowires at various nominal Al contents with high material quality has been acquired. These branchless structures are ideal hosts for narrower bandgap GaAs quantum dots, promising for non‐classical light‐emitting applications.

Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials

open access: yesAdvanced Optical Materials, Volume 14, Issue 2, 14 January 2026.
Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).
