Controlling Twisted Angles in Directly Grown MoS2 Bilayers via Tilt Grain Boundary Engineering

Advanced Science, EarlyView.
In this study, the stacking configurations and the growth mechanism of twisted bilayer (TB) MoS2 are systematically investigated, revealing that the relative rotation angle between the two layers is guided by the tilt grain boundary (GBs) of the bottom layer.

Circular Polarimetric Imaging with a Metamaterial Integrated Long‐Wavelength Infrared Focal Plane Array

Advanced Science, EarlyView.
A quantum well infrared photodetector based long‐wavelength infrared division‐of‐focal‐plane‐array circular polarimeter featuring a 320 × 256 pixel array integrated with a chiral meta‐mirror structure array is established. The device achieves a circular polarization extinction ratio of 5.67, a 9.13‐fold enhancement in responsivity, a noise equivalent ...

Me‐4PACz Functionalized MXene for Halide Perovskite Solar Cells

Advanced Science, EarlyView.
Functionalized Ti₃C₂ MXene nanoneedles with Me‐4PACz employed at the interface between perovskite and Spiro‐OMeTAD, improve charge extraction, energy alignment, and surface hydrophobicity. Devices show boosted PCE (21.5%) and operational stability (T88 = 1000 h, ISOS‐L‐1), highlighting MXene:Me‐4PACz as a powerful strategy for simultaneously improving ...

High Electron Charge Carrier Mobility in the Nematic Phase of a Roof‐Shaped Nematogen with Optimum Molecular Biaxiality

Advanced Science, EarlyView.
Liquid Roofs. Biaxial roof‐shaped mesogens self‐assemble in a nematic phase of a broad temperature range exhibiting high TOF electron mobilities. These mesogens possess the almost optimum biaxial aspect ratio. The results from X‐ray, polarized optical microscopy, modeling, and TOF data agree with biaxiality of small domains and transient nematic phase ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films

Advanced Electronic Materials, EarlyView.
This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...

Vertical Phase Separation in Blended Organic Semiconducting Films and Impact on Their Electrical and Direct X‐Ray Detection Properties

Advanced Electronic Materials, EarlyView.
The composition of blends of 1,4,8,11‐tetramethyl‐6,13‐triethylsilylethynyl pentacene (TMTES) and polystyrene (PS) to be used in Organic Field‐Effect Transistors (OFETs) is optimized to achieve and enhance thin film crystallinity and a reduced charge trap density at the semiconductor/dielectric interface.

Direct‐Write Printed Contacts to Layered and 2D Materials

Advanced Electronic Materials, EarlyView.
It is demonstrated that direct‐write printing is a viable method to fabricate devices on different 2D and layered materials yields Ohmic contacts in a single step, as compared to multi‐step lithography processes which often yield poor contacts. Printed devices perform exceedingly well with gating, temperature cycling, and in magnetic fields.
