Abstract Antimony selenide (Sb 2 Se 3 ) has garnered significant attention with its extraordinary optical and optoelectronic properties for devices such as broadband photodetectors. The trends emerge in the synthesis of Sb over a semiconducting substrate direct formation heterostructures, which facilitate pn junction self‐powered photodetector. 1D nanorods are preferred to boost charge carrier transport along longitudinal direction well absorption by light trapping. Great challenges remain...

A rarely discussed phenomenon in the realm of photocatalytic materials involves presence gradient distributed dopants and defects from interior to surface. This intriguing characteristic has been successfully achieved case ZnS through incorporation atomic monovalent copper ions (Cu+) concurrent sulfur vacancies (Vs), resulting a photocatalyst denoted as G-CZS1–x. Through cooperative action these Cu Vs, G-CZS1–x significantly extends its photoabsorption range encompass full spectrum (200–2100...

Conducting polymers have recently been suggested as thermoelectric materials for use in large-area thermogenerators. To help assessing the feasibility of this electrical conductivity and Seebeck coefficient a series heavily doped regioregular poly(3-hexylthiophene) films are measured between 220 370 K. $p$-type chemical doping up to 34% is accompanied by introduction negatively charged counterions, ${\text{PF}}_{6}^{\ensuremath{-}}$. The counterions produce disordered environment within...

Abstract P2‐phase layered cathodes play a pivotal role in sodium‐ion batteries due to their efficient Na + intercalation chemistry. However, limited by crystal disintegration and interfacial instability, bulk failure plague electrochemical performance. To address these challenges, structural enhancement combined with surface modification is achieved through trace Y doping. Based on synergistic combination of experimental results density functional theory (DFT) calculations, the introduction...

Developing high-performance organic-inorganic ultraviolet (UV) photodetectors (PDs) has attracted considerable attention. However, this development been hindered due to poor directional charge-transfer ratios in transport layers, excessive costs, and an ambiguous underlying mechanism. To tackle these challenges, we constructed a heterojunction of economic Mg-doped ZnO (MgZnO) nanorods poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) [PEDOT:PSS (P:P)] that utilizes dipole field-driven...

Zero-sodium-excess solid-state batteries (ZSBs) are promising to overcome the disadvantage of low energy density for Na-ion batteries, but interfacial issues between electrolytes and current collectors remain bottlenecks their practical applications. Herein, we report a self-regulated stratification artificial interphase through conversion reaction MgF2 modification layer Na metal. Ascribed huge adsorption difference Al–Mg Al–NaF, sodiophilic Mg concentrated at bottom side served as...
