Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Analyzing Electronic Excitations and Exciton Binding Energies in Y6 Films

open access: yesAdvanced Functional Materials, EarlyView.
The Y6 molecule is used for increasing the efficiency of organic solar cells. The exciton binding energy is calculated for ensembles of Y6 molecules that are representative of the typically used films. The calculations show that the excitons typically spread out over many molecules.

Photoswitchable Conductive Metal–Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
A conductive material where the conductivity can be modulated remotely by irradiation with light is presented. It is based on films of conductive metal–organic framework type Cu3(HHTP)2 with embedded photochromic molecules such as azobenzene, diarylethene, spiropyran, and hexaarylbiimidazole in the pores.
