Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

Advanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.

Magnetic and Structural Response Tuned by Coexisting Mn Concentration‐Dependent Phases in MnBi2Te4 Thin Film Grown on GaAs(001) by Molecular Beam Epitaxy

Advanced Functional Materials, EarlyView.
The study explores structural and magnetic properties of one of the most recent topological quantum materials (MnBi2Te4). The Mn‐poor structure leads to stacking faults (quintuple layer ‐ QL of Bi2Te3 formation instead of a septuple layer ‐ SL of MnBi2Te4), resulting in a coexistence between weak antiferromagnetism and ferromagnetism.

Ultra‐Sensitive Short‐Wave Infrared Organic Photodetectors Enabled by a π‐Conjugation Extended Proquinoid Electron Acceptor

Advanced Functional Materials, EarlyView.
A novel proquinoid‐type electron acceptor, TQC‐4Cl, with an ultra‐narrow bandgap of 1.01 eV and spectral response beyond 1200 nm enables organic SWIR photodetectors. The optimized devices show a high EQE of 13.66% and high specific detectivity over 1012 Jones at 1200 nm under −0.5 V reverse bias with outstanding thermal stability, highlighting their ...
