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

open access: yesSmall, 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 ...

Grain‐Size‐Controlled Resistive Switching Memories Enabling Domain‐Specific Functionality for Real‐Time Video Signal Processing

open access: yesSmall, EarlyView.
Grain‐size‐controlled resistive switching memory arrays based on Sn‐halide perovskite thin films are realized via a photo‐thermochemical process that creates lateral grain‐size gradients. The arrays exhibit domain‐specific volatile threshold switching and short‐term neural dynamics, enabling nonlinear conductance, tunable relaxation, integrate‐and‐fire,

Super‐High Sodium‐Ion Conductivity of Na2.9Sb0.9W0.1S4 at Low Pressures by Systematic Pressure and Temperature Treatments

open access: yesSmall, EarlyView.
Systematic pressure and temperature treatment of the sodium ion electrolyte Na2.9Sb0.9W0.1S4 enabled deep insight into the effects of these parameters on the sodium conductivities and their impedance‐spectroscopic measurements, and afforded a material exhibiting a record superionic conductivity of 44.7 mS cm−1 at pressures down to 18 MPa and an ...

Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.
