Self‐Powered Broadband High‐Responsivity Photodetectors: p‐(CuS)x(ZnSe)1−x/p‐Si Isotype Heterojunction

Small, EarlyView.
This study reports a self‐powered broadband photodetector based on compositionally tuned p‐(CuS)x(ZnSe)1−x/p‐Si isotype heterojunctions. Increasing the CuS ratio improved the film crystallinity and produced a denser, more homogeneous nanopillar morphology, enhancing light absorption.

Carbon‐Modified SnS2/g‐C3N4 S‐Scheme Heterostructure with Enhanced Interfacial Charge Transfer for Efficient Photocatalytic Reduction of Cr(VI) and 4‐Nitrophenol

Small, EarlyView.
The S‐scheme of SnS2‐C/g‐C3N4 heterostructure enables Photocatalytic Cr(VI) and 4‐NP reduction. ABSTRACT Hexavalent chromium (Cr(VI)) and 4‐nitrophenol (4‐NP) are persistent and highly toxic water pollutants that require efficient treatment under mild conditions. In this work, L‐cysteine‐derived carbon‐modified SnS2 (SnS2‐C) was prepared hydrothermally

Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

Small Methods, EarlyView.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.

Unveiling Ca9N4Te3: A New Motif in Alkaline‐Earth Metal Chalcogenide Nitrides: A Combined Experimental and Computational Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The unique double monocapped trigonal cupola coordination polyhedra of Te(2) atoms inside the crystal structure of Ca9N4Te3. Green, moisture‐sensitive Ca9N4Te3 was obtained from Ca/Na flux at 1173 K as a by‐product of reddish‐brown Ca6N2Te3 and crystallizes in the trigonal space group R3¯$\overline{3}$ (No. 148, Z = 3).

Interfacial and Ligand Dual Engineering Toward Energy‐Saving Hydrogen Production Coupled with Sulfion Degradation

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Using a coordinated regulation strategy of interface and ligand, we developed a nickel cobalt sulfide/carboxylate ligand‐modified nickel cobalt hydroxide composite (NiCo‐S/NiCo‐OH‐CL) with abundant heterointerfaces. Owing to the porous network, sulfur‐repellent hydrophilic surface, and dual electronic structure regulation, the coupled electrolysis ...
