Thermionics in Topological Materials

open access: yesAdvanced Materials, EarlyView.
Thermionics is one of the fundamental energy conversion mechanisms in solid state systems. Recent development in topological materials opens new avenues in developing thermionic systems and devices. Due to the linear energy dispersion and topological protection of charge transport, these new materials are promising candidates for high efficiency ...

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Unraveling the Impact of Electrosorbed Ions on the Scaling Behavior of Fast‐Charging Dynamics of Nanoporous Electrodes Toward Digital Design of Iontronic Devices

open access: yesAdvanced Materials, EarlyView.
Electrosorbed ions under nanoconfinement (see TOC figure) critically reshape electrochemical potentials and impact ion transport in porous electrodes. By integrating modified Poisson–Nernst–Planck simulations with multilayered graphene membrane experiments, this study establishes a scaling relation and reveals electrosorption‐enhanced transport ...

Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

open access: yesAdvanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

Ferrofluid‐Based Bioink for 3D Printed Skeletal Muscle Tissues with Enhanced Force and Magnetic Response

open access: yesAdvanced Materials Interfaces, EarlyView.
The integration of ferrofluid consisting of citrated iron oxide nanoparticles into muscle cell‐laden ink to obtain magnetic‐responsive muscle tissue (i.e., ferromuscle) allows not only an easy printability process to integrate magnetic components in 3D printed tissues, but also impacts positively in terms of tissue differentiation and increased force ...

Emergent Ferromagnetism at LaFeO3/SrTiO3 Interface Arising from a Strain‐Induced Spin‐State Transition

open access: yesAdvanced Materials Interfaces, EarlyView.
Strain at the LaFeO3/SrTiO3 interface induces spin‐state disproportionation, creating a checkerboard pattern of low‐ and high‐spin Fe3+ ions. This unusual configuration leads to interfacial ferromagnetism in an otherwise antiferromagnetic insulator. Using electron microscopy, spectroscopy, and density functional theory, this work reveals a new route to
