Cu+‐Driven Formate Selectivity in Oxidation‐State‐Dependent CO2 Reduction on Cu2O|Graphene

open access: yesSmall, EarlyView.
A Cu2O|graphene heterostructure enables interfacial electronic self‐regulation that stabilizes catalytically active Cu+ species under cathodic CO2 reduction conditions. Suppressed over‐reduction preserves structural integrity and promotes *OCHO pathway, resulting in durable and highly selective electrochemical conversion of CO2 to formate.

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

open access: yesSmall, 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.

Deterministic Switching‐Path Engineering of CMOS‐Integrated 2D Memristors for Neuromorphic Computing

open access: yesSmall, EarlyView.
Deterministic grain‐boundary engineering in 2D MoTe2 defines resistive switching paths, while CMOS transistors impose gate‐tunable current compliance in a monolithically integrated 1T–1 M array. The resulting artificial synapses show stable, linear, and low‐variation analog weight updates, illustrating how materials‐level defect control can be ...
