Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide

open access: yesAdvanced Functional Materials, EarlyView.
The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...

Control of Ferromagnetism of Vanadium Oxide Thin Films by Oxidation States

open access: yesAdvanced Functional Materials, EarlyView.
The nonstoichiometric VOx exhibits a distinct ferromagnetic hysteresis loop and demonstrates a high magnetic susceptibility (χ=dMdH$ = \frac{{dM}}{{dH}}\;$∼10). Micromagnetic simulations show the results of the “partial volume fraction ferromagnetic phase model” for VOx/Co/Pt structure.

Minuscule Amounts of Pt Single Atoms Selectively Loaded on Minor (101) Facet of Anatase Crystallites Enables Outstanding Utilization Efficiency for Photocatalytic H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
Ar–H2 annealing triggers redistribution of pre‐deposited Pt single atoms (SAs) on faceted anatase nanosheets, with selective SAs accumulation on the minor (101) facetsthus the co‐catalytic SA‐sites are positioned only where they are needed, i.e. at the electron exit facets.

The Role of Fluorine‐Functionalized Organic Spacers for Defect Passivation and Low‐Dimensional Phase Formation in 3D MAPI Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
Fluorine‐functionalized organic spacers (2F, 3F, 5F) are investigated to identify as optimal passivation agents for 3D MAPI perovskite solar cells (PSCs). The study highlights how altering fluorine positioning affects defect passivation, low‐dimensional phase (LDP) formation, and stability, emphasizing its role in molecular interactions and offering ...
