Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors

Advanced Materials, EarlyView.
Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

Synthesis of Bulk Superconducting LiNbO2 Crystals Through CaH2 Reduction

Advanced Materials, EarlyView.
CaH2 reduction reconstructively transforms insulating LiNbO3 single crystals into superconducting bulk LiNbO2 with a critical temperature of Tc = 14.4 K. Scanning electron microscopy reveals large‐volume, high‐yield phase conversion. Magnetization measurements demonstrate a robust ∼ 77% Meissner shielding fraction, establishing bulk superconductivity ...

Wafer‐Scale Direct Growth of Ultraclean Monolayer Amorphous Carbon on c‐Sapphire by Remote Catalytic Dehydrogenation

Advanced Materials, EarlyView.
Remote catalytic dehydrogenation enables the direct growth of monolayer amorphous carbon on a 2‐inch sapphire wafer by thermal CVD. Spatial separation of the catalyst from the growth substrate eliminates metallic residue and post‐growth processing, yielding a wafer‐scale uniform film with a random polygonal sp2‐hybridized carbon network that exhibits ...
