Composition Control in CuInZnS2 Nanocrystals by Cation Exchange and Their Phase Transfer

ChemNanoMat, Volume 12, Issue 10, October 2026.
This work elucidates the composition‐defining parameters for CuInZnS2 (CIZS) nanocrystals (NCs) prepared by a cation exchange reaction. Investigations focus on their cation shares and size, which influence both the absorbance and the bandgap. Furthermore, a novel ligand exchange route from 1‐dodecanthiol to 11‐mercaptoundecanoic acid is shown, thereby ...

Epitaxial Integration of III–V Membrane Photodetectors With Lateral p–i–n Junctions on the Silicon‐On‐Insulator Waveguide Platform

Laser &Photonics Reviews, Volume 20, Issue 19, 7 October 2026.
Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

A Four‐Terminal TiO2−x Memristor Architecture Enabling Multidimensional Associative Learning

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
This work demonstrates bidirectional Pavlovian conditioning in a single four‐terminal TiO2−x memristor device where two‐dimensional oxygen vacancy control and non‐filamentary resistive switching are realized. Extending this approach, multiple memristors arranged in an array autonomously perform multidimensional associative learning of two‐dimensional ...

Photolithographic Patterning of Colloidal Quantum Dots Enabled by Plasma‐Induced Ligand Polymerization

Advanced Materials Technologies, Volume 11, Issue 17, 3 September 2026.
Plasma‐induced ligand polymerization on colloidal quantum dots (QDs) renders them resistant to organic solvents, enabling conventional photoresist‐based photolithography. This approach achieves microscale patterning with feature sizes down to 3 µm, preserving the optical properties of the QDs and offering a simple and scalable route for QD‐based ...
