Deuteration‐functionalized self‐assembled monolayers for UV‐durable perovskite solar cells

open access: yesInfoMat, EarlyView.
Modification with deuterophenyl groups has been demonstrated to be an effective strategy for the construction of SAMs. The impressive PCE of 26.34% is by far one of the highest values for PSCs with the carbazole‐based SAMs as HTLs. This UV resistance performance represents the highest level of performance reported to date for PSCs using SAMs as HTLs ...

Large Unsaturated Magnetoresistance in Gated MoS2 Flakes

open access: yesSmall, EarlyView.
Magnetotransport investigation of layered MoS2 crystals in field‐effect devices reveals strong dependence on thickness and carrier density. Monolayer MoS2 exhibits the highest magnetoresistance of 680%. A combination of density functional theory and Boltzmann transport equation simulations shows that band transport is not causing the magnetic behavior,

Efficient Photocatalytic Hydrogen Evolution Enabled by Defect‐ and Interface‐Induced Dual Built‐in Electric Fields in a ZnIn2S4/1T‐2H WS2 Heterojunction

open access: yesSmall, EarlyView.
An N, Sv‐ZnIn2S4/1T‐2H WS2 composite photocatalyst is constructed via an in situ hydrothermal‐solvothermal strategy, simultaneously forming a defect‐induced p‐n homojunction in ZnIn2S4 and a type‐II heterojunction with hybrid 1T/2H WS2. The coupled dual built‐in electric fields promote charge separation and direct photoexcited electrons toward sulfur ...

Plea for Defect Chemistry: The Fundamental Role of the Chemically Excited States in Solid‐State Chemistry and Beyond

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
In solids, the point defects take the role that in water is held by H3O+, OH−, and solutes. While the chemical ground structure (crystallographic structure) plays the role of the matrix, it is the chemically excited states (dissociation, disorder) that breathe life into the matter.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, Volume 36, Issue 27, 2 April 2026.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
