Single Cu Atom Sites on Co3O4 Activate Interfacial Oxygen for Enhanced Reactivity and Selective Gas Sensing at Low Temperature

open access: yesSmall, EarlyView.
Atomically dispersed Cu sites on Co3O4 nanoparticles establish well‐defined Cu–O–Co interfacial linkages that promote lattice oxygen activation at markedly reduced temperatures. This structural and electronic modulation yields over twenty‐fold higher low‐temperature formaldehyde sensing responses than CuO nanoparticle analogues, enabling selective and ...

Strain‐Field‐Induced Bandgap Opening in Bilayer Graphene

open access: yesSmall, EarlyView.
Bandgaps of up to 50 meV are opened in bilayer graphene through periodic in‐plane strain fields imposed by a three‐layer graphene/organic 2D crystal/graphene heterostructure. The bandgap originates not from bilayer formation itself, but from bond‐length modulation at domain boundaries.

Electrically Tunable Tunneling and Spectral Response in WSe2/h‐BN/CdSe/Graphene Heterostructure

open access: yesSmall, EarlyView.
In the WSe2/h‐BN/CdSe quantum dot/graphene heterostructure, the graphene voltage dynamically tunes the tunneling barrier and energy alignment across the h‐BN layer. The bias‐dependent Fermi‐level alignment enhances the tunneling density of states, leading to efficient extraction of photo‐excited electrons from QDs into WSe2 and graphene.

Synergistic Pyroelectric‐Bolometric Coupling in Tellurene Nanowire for Energy‐Efficient Artificial Vision

open access: yesSmall, EarlyView.
Synergistic pyroelectric–bolometric coupling in Tellurene nanowires enables efficient photothermal conversion and self‐driven synaptic functionality. Edge‐induced polarization and temperature‐dependent resistance cooperatively generate enhanced transient responses and multilevel conductance states.
