Interaction of Te and Se interlayers with Ag or Au nanofilms in sandwich structures

open access: yesBeilstein Journal of Nanotechnology, 2019
Noble metal nanolayers on flat substrates are often deposited with the use of semiconductor interlayers, which may strongly interact with the noble metal overlayer. We investigated the crystallinity, atomic concentration profile and optical parameters of

From topological insulators to superconductors and Confinement

open access: yes, 2012
Topological matter in 3D is characterized by the presence of a topological BF term in its long-distance effective action. We show that, in 3D, there is another marginal term that must be added to the action in order to fully determine the physical ...

Tribenzyl Organic Cations Carried Multidentate X‐Type Lewis Soft Base for High‐Performance Foldable Perovskite Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
This study proposes tribenzyl organic cation carried multidentate X‐type Lewis soft base to enhance adhesion and passivate defects simultaneously, aiming to achieve foldable and efficient perovskite nanocrystal‐based light‐emitting diodes. The resulting pure red F‐PeLEDs exhibit a recorded high EQE of 16.2% and robust mechanical properties to endure ...

Enhanced dielectric properties and energy storage of the sandwich-structured poly(vinylidene fluoride-co-hexafluoropropylene) composite films with functional BaTiO(3)@Al(2)O(3) nanofibres

open access: yesIET Nanodielectrics, 2019
Polymer-based composites with ceramic fillers could combine the advantages of both, which can be potentially used in electrical and electronic technology. In this work, the barium titanate (BaTiO(3)) nanofibres and the core–shell structured BaTiO(3)@Al(2)

Accurate Modelling of Left-Handed Metamaterials Using Finite-Difference Time-Domain Method with Spatial Averaging at the Boundaries

open access: yes, 2007
The accuracy of finite-difference time-domain (FDTD) modelling of left-handed metamaterials (LHMs) is dramatically improved by using an averaging technique along the boundaries of LHM slabs. The material frequency dispersion of LHMs is taken into account

Nonlocal Conduction in a Metawire

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
A 1D metawire composed of twisted copper wires is designed and realized. This metamaterial exhibits pronounced effects of nonlocal electric conduction according to Ohm's law. The current at one location not only depends on the electric field at that location but also on other locations.

Field dependent permittivity of composite materials containing ferromagnetic wires

open access: yes, 2003
The effective permittivity of composites containing ferromagnetic microwires has been analysed within a one-particle approximation, by considering a wire piece as an independent scatterer and solving the scattering problem with the impedance boundary ...

10 Years Development of Potassium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of
