Soft and Transient Bioelectronics Enabled by Polymer‐Free Ti3C2Tx MXene Hydrogels

Advanced Materials, EarlyView.
We present Ti3C2Tx MXene hydrogel (MXgel) bioelectronics, a soft, flexible, and fully transient platform for high‐fidelity neural recording and stimulation. MXgel bioelectronics exhibit exceptional electrical conductivities, low electrochemical impedances, and high charge injection capacities.

Theoretical study of polarization-doped GaN-based light-emitting diodes

, 2011
Insufficient hole injection is a major impediment to the luminescence efficiency of III-nitride light-emitting diodes(LEDs). In our previous work by Zhang[Appl. Phys. Lett.97,062103(2010)], high-density mobile three-dimensional hole gas is obtained in Mg-

Ferrocene‐Based Self‐Assembled Monolayers Enable Ultra‐High Specific Detectivity in Perovskite Photodetectors

Advanced Materials, EarlyView.
We report perovskite photodetectors with record specific detectivities exceeding 1013 Jones with a novel molecular design strategy to functionalize self‐assembled monolayers (SAMs) with ferrocene (Fc) derivatives. Fc‐SAM‐based devices also exhibit strong operational stability and enable data transmission rates exceeding 1 Mbps in a LiFi system ...

Multimodal Bioinspired Self-Healing Composites Enabling Durable and High-Efficiency Wearable Perovskite Light-Emitting Diodes. [PDF]

Adv Sci (Weinh)
Butterfly wing–inspired intrinsically self‐healing polymer interlayers enable flexible perovskite optoelectronics with high luminance, strain‐insensitive stability, and environmental resilience. These hierarchically structured films redistribute mechanical stress, suppress defect formation, and maintain performance under repeated bending, paving the ...

Efficient in‐Plane Exciton Transport in a Discontinuous Layered Lead‐Bromide Perovskite

Advanced Materials, EarlyView.
A new class of two‐dimensional lead‐bromide perovskite based on monovalent 4‐aminomethylbenzoic acid cations is presented, featuring a discontinuous inorganic layer. Despite the discontinuous lattice, transient photoluminescence microscopy demonstrates efficient though strongly anisotropic in‐plane exciton transport.
