Bio‐inspired artificial retina with receptive fields for in‐sensor multiply‐and‐accumulate operations

InfoMat, Volume 8, Issue 8, August 2026.
We developed a bio‐inspired artificial retina in which curved artificial receptive fields composed of perovskite photoconductors perform multiply‐and‐accumulate operations through in‐sensor computing. This architecture simultaneously realized the structural efficiency of human eyes (compact single‐lens imaging system) and functional advantages of ...

First‐Principle Analysis of the Structural, Elastic, Electronic, and Optical Properties of Novel AHgF3 (A = K and Fr) Perovskite

Nano Select, Volume 7, Issue 8, August 2026.
The evaluation of the physical properties of novel KHgF3 and FrHgF3 perovskites is explored. Both compounds are thermodynamically stable and mechanically ductile. Featuring narrow band gaps around 0.53–0.60 eV, these materials show strong potential for use in flexible infrared‐to‐visible optoelectronics and energy conversion devices.

Engineering and Enhancing the Spectral Response of nipip HIT Photodetectors

Nano Select, Volume 7, Issue 8, August 2026.
Engineering top a‐Si:H through ambient oxidation or partial removal of a‐Si:H effectively tunes the photodetector spectral response. Etching allows direct ITO contact with crystalline silicon, enhancing substrate contributions. This approach provides a desirable tunability for broadband UV‐to‐NIR photodetection on silicon‐based platforms, as validated ...

Self‐Powered Broad‐Spectrum UV Photodetectors Based on TiO2/Graphene/Acid‐Doped Polyaniline Heterojunction

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The development of high‐performance, self‐powered ultraviolet photodetectors (UVPDs) is crucial for the practical application of low‐power‐consumption optoelectronic devices. However, achieving both broad‐spectrum detection and high sensitivity remains a challenge.

Structure‐Controlled Cyclopentadithiophene Derived Non‐Fullerene Acceptors for Efficient Near‐Infrared Organic Photodetectors

Small, Volume 22, Issue 43, 3 August 2026.
This work demonstrates high‐performance solution‐processed NIR OPDs using DTP‐ and DTTP‐based NFAs (OC and SC), where donor‐core engineering enables tunable absorption and balanced optoelectronic properties; notably, DTP‐based devices achieve broad NIR response, low dark current, and high detectivity, highlighting their potential for advanced NIR ...

A comparative study of broadband PbS quantum dots/graphene photodetectors with monolayer and bilayer graphene

Nano Express
Colloidal quantum dots (QDs)/graphene nanohybrids provide a unique platform to design photodetectors of high performance. These photodetectors are quantum sensors due to the strong quantum confinement in QDs for spectral tunability, and in graphene for ...

Cathodic Cage Plasma Deposition of Nanostructured Cu–Fe–Se Coatings on Poly(methyl Methacrylate)

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Nanostructured Cu–Fe–Se coatings are deposited on PMMA by a modified cathodic cage plasma process, enabling low‐temperature deposition on polymer substrates. A transition from discontinuous to compact morphology is observed with temperature, with optimal properties at 200°C, where improved CuFeSe2‐type bonding, lowest sheet resistance, and favorable ...
