Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

Small, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...

Flattening Energy Puddles for Enhanced Charge Transport in Wrinkled WSe2

Small, EarlyView.
Strain‐inducing wrinkles in 1L‐WSe2 create carrier‐trapping energy puddles. Trioctylphosphine selenide (TOPSe) selectively passivates Se vacancies at these wrinkle sites, while steric hindrance suppresses basal‐plane reaction. Comprehensive suite of space‐resolved spectroscopic techniques reveals reduced nonradiative recombination, longer exciton ...

Combinatorial Synthesis of BaCu2Se2 Thin Films: Effect of Composition on Crystal Structure and Optoelectronic Properties

Small, EarlyView.
The emerging BaCu2Se2 semiconductor compound is synthesized in combinatorial thin film libraries for fast screening of its fundamental properties related to the application in sustainable energy sources. Ba‐rich and Cu‐rich compositions are explored.

Quasi‐BIC and Reflective Mode Coupling Drives SHG Beyond the Q Factor Limit

Small, EarlyView.
An analytical expression is developed to relate second‐harmonic generation to both the resonance Q factor and absorptance. Simulations and experiments on a dual‐resonance 3R‐MoS2 metasurface validate the formula, showing that absorptance engineering provides an effective route to enhance SHG beyond conventional Q‐only design.

Tailoring the Melting and Glass Transition Behavior of Zeolitic Imidazolate Frameworks via Ammonium Halide Salts

Small, EarlyView.
Ammonium halide salts serve as inorganic modifiers that lower the melting and glass transition temperatures of zeolitic imidazolate frameworks, enabling centimeter‐scale hybrid glasses and melt processing of otherwise unmeltable ZIF‐8. In situ imaging and pair distribution function analysis reveal salt infiltration, Zn─N bond disruption, and Zn–halide ...
