Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

Advanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...

Stable P‐Type PbS Quantum Dot Ink for all‐Blade‐Coated Short‐Wavelength Infrared Photodiodes

Advanced Materials, Volume 38, Issue 15, 12 March 2026.
Stabilization of p‐type PbS quantum dot ink is achieved through hydrogen bonding between fluorinated alcohols solvent and the MP ligand, allowing a six‐day shelf‐life. The solvent does not compromise pre‐deposited layers, enabling fully blade‐coated photodiodes in both n–p and p–n architectures, with enhanced detectivity and bandwidth compared to layer‐

High‐Performance Photodetectors of Quasi‐2‐Dimensional Epitaxially‐Connected Quantum Dot Superlattices

Advanced Optical Materials, Volume 14, Issue 11, 20 March 2026.
High electrical conductivity in a monolayer of a well‐ordered, epitaxially connected quantum dot superlattice enables the demonstration of a photodetector with high responsivity and detectivity, as well as faster response. Although epitaxially connected, these quantum dot superlattices have some of their quantum confinement natures preserved, as ...

Dilution Effect for High‐Performance Multiple‐Component Near‐Infrared Organic Photodetectors

Advanced Science, Volume 13, Issue 16, 18 March 2026.
The dilution effect in multi‐component organic photodetector effectively suppresses non‐radiative decay and minimizes dark current, while energy‐level‐offset‐governed electron transfer between acceptors maintains efficient charge transport. This synergistic mechanism collectively enables remarkable device performance, including high detectivity and ...
