MOCVD‐Grown MoS2 Wafers as a Transfer‐Free Platform for Top‐Gate Devices via Dry Interface Engineering

open access: yesAdvanced Materials, EarlyView.
We reveal the electronic origin of hidden interfacial doping in monolayer MoS2 grown by MOCVD, identifying sulfate related and water like species as intrinsic donors. Through dry interface engineering approach, we demonstrate MOCVD‐grown single‐crystal MoS2 wafers as a transfer‐free platform for the reliable evaluation of intrinsic gate stacks and ...

Sub‐Diffraction Nanolithography of Halide Perovskite via Reversible All‐Optical Crystallization–Decomposition

open access: yesAdvanced Materials, EarlyView.
A reversible, all‐optical modulation strategy enables resist‐free, sub‐diffraction nanolithography of halide perovskite films. Leveraging 800 nm fs laser‐induced crystallization and 365 nm laser driven decomposition, reconfigurable patterning achieves feature sizes down to 93.5 nm. This chemistry‐free approach offers dynamic control over optoelectronic

Ligand‐Mediated Shape Engineering of SWIR InAs Colloidal Quantum Dots for Photodetector Applications

open access: yesAdvanced Materials, EarlyView.
The table of contents: A robust ligand‐engineering strategy is introduced for SWIR InAs CQDs synthesized from amino‐arsine precursors. Bulky OA ligands induce controlled shape evolution, allowing access to >1700 nm absorption under mild conditions. Halide‐based inkification enables photodetectors with 19.1% EQE at 1300 nm and detectivity exceeding 1010

Ligand Engineering for Precise Control of Ultrathin CsPbI3 Nanoplatelet Superlattices for Efficient Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.
