Imaging the Thickness‐Dependent Formation of Schottky Barriers in Metal–Semiconductor van der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Using nanobeam photoemission, we demonstrate imaging of the in‐plane and out‐of‐plane electric field landscape within a metal–semiconductor van der Waals heterostructure. We provide evidence for Schottky barrier formation that depends on the semiconductor thickness. ABSTRACT Achieving high‐performance optoelectronic devices based on two‐dimensional van

Solution‐Processed Mn‐Doped 2d Perovskite Wavelength Shifters for Noble‐Liquid Photon Detection

Advanced Functional Materials, EarlyView.
Solution‐processed Mn2+‐doped PEA2PbBr4 two‐dimensional perovskite films are demonstrated as large‐area wavelength shifters for noble‐liquid photon detectors. Mn2+ incorporation introduces a broad emission band at ∼620 nm with a large Stokes shift, suppressing self‐absorption and matching SiPM sensitivity.

Memristive‐Gated RC‐Delay Synaptic Transistors for Time‐Encoded Analog in‐Memory Computing

Advanced Functional Materials, EarlyView.
A Memristive‐Gated Transistor for Time‐Encoded Analog In‐Memory Computing — By exploiting the RC delay of a self‐rectifying interface‐type memristor, nonlinear I–V distortion is structurally bypassed, enabling 3‐bit nonvolatile memory, spike‐timing‐based analog encoding, and hardware‐calibrated reservoir‐computing validation within a unified device ...

Boosting Conversion Efficiency in Zn3P2/InP Solar Cells Via Nanoscale Junction Engineering

Advanced Functional Materials, EarlyView.
This study demonstrates the efficacy of selective area epitaxy (SAE) in enhancing the conversion efficiency of a Zn3P2${\rm Zn}_3{\rm P}_2$/InP heterojunction solar cell. The impact of the SAE pattern dimensions on the performance parameters is investigated. Small size opening limits Jsc because of current crowding whereas large size opening limits Voc

Effects of Black Silicon Surface Morphology Induced by a Femtosecond Laser on Absorptance and Photoelectric Response Efficiency

Photonics
In this study, the effects of variations in the height (h) and bottom radius (r) of black silicon microstructures on their absorptance and photoelectric response efficiency were analyzed.

Mechanotransduction of Magnetically Applied Forces Leads to Mechanical Stiffening of Platelet‐Rich Plugs

Advanced Healthcare Materials, EarlyView.
A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)
