Synthesis of nanoparticles of Y(OH)CO3 and Y2O3 using liquid interfaces and modification of their surface by palladium

open access: yesТонкие химические технологии, 2011
The nano-composite materials with different morphology and structure, including yttrium basic carbonate or yttrium oxide and palladium metal are obtained. The optimal conditions for synthesis of stable nanoparticles of yttrium basic carbonate are defined.

Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

Furan‐Substituted Phosphine‐Oxide as an Efficient Interfacial Modifier for Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.

Rate‐Adaptive Site Transformation Catalyst for Parallel Water Dissociation and Hydrogen Adsorption in Alkaline Hydrogen Evolution

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Polymer Network Modified Perovskite for High‐Performance Pure Blue Light‐Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
A polymer network of poly(4‐vinylphenol) (PVPh) is introduced to improve pure blue perovskite light‐emitting diodes. PVPh effectively passivates defects, enhances film morphology, reduces lattice strain, and suppresses ion migration. These effects lead to record device performance, achieving 9.82% external quantum efficiency and stable blue emission at
