In this work, we apply a molecular dynamics simulation of Ag-nanoparticle-doped epoxy resin to analyze in depth the micro-mechanisms nanodielectric. The results show that when Ag nanoparticles with radius 10Å are used as dopants, periodically arranged atoms ~4.5-Å-thick surface layer have become amorphous. This modification interface depends on temperature and nanoparticle size leads an polariz...

Mobile ions in amorphous materials have been a serious object of investigation [1], and their dynamics in disordered hosts constitute one of the major unsolved problems in the field of solid state ionics. Certain compositions of silver doped GeSe glasses (close to compositions reported here) have practical potential for novel computer memory devices [2]. The structure of the Ge– Se– Ag glasses ...

Title of Document: FORMATION AND CHARACTERIZATION OF TRANSVERSELY MODULATED NANOSTRUCTURES IN METALLIC THIN FILMS USING EPITAXIAL CONTROL Brad Michael Boyerinas, Ph.D, 2013 Directed By: Hugh A. Bruck, Professor, Department of Mechanical Engineering This thesis describes a fundamental investigation into the formation, characterization, and modeling of epitaxially-controlled self-assembly at the ...

BACKGROUND The hydrothermal method was used as a new approach to prepare a series of Ag-doped Cd0.1Zn0.9S photocatalysts. The effect of Ag doping on the properties and photocatalytic activity of Cd0.1Zn0.9S was studied for the hydrogen production from water reduction under visible light irradiation. RESULTS Compared to the series prepared by the co-precipitation method, samples prepared by th...

Metal-doped ZnO [MZO] thin films show changes of the following properties by a dopant. First, group III element (Al, In, Ga)-doped ZnO thin films have a high conductivity having an n-type semiconductor characteristic. Second, group I element (Li, Na, K)-doped ZnO thin films have high resistivity due to a dopant that accepts a carrier. The metal-doped ZnO (M = Li, Ag) films were prepared by radi...

In this work, we used density functional theory (DFT) and linear response time-dependent DFT (LR-TDDFT) to investigate the stability, electronic structure, and optical properties of Au-doped [Ag29-xAux(BDT)12(TPP)4]3- nanoclusters (BDT: 1,3-benzenedithiol; TPP triphenylphosphine) with x = 0-5. The aim of this work is to shed light on the most favorable doped structures by comparing our results ...

Moreover, to further boost the device effi ciency, a resonant optical cavity can be created between the transparent thin Ag fi lm and an opaque back contact metal electrode, thus trapping light inside the active layer and enhancing its light absorption. [ 22 ] However, Ag follows 3D growth mode: during deposition, Ag atoms fi rst agglomerate into isolated islands, and as the deposition continue...

Abstract Electrochemical CO 2 reduction is an environmentally sustainable way for conversion and utilization, the development of which needs highly efficient catalysts. Ag‐based materials are one kind electrocatalyst that catalytically active to CO. In this work, Ag clusters were fabricated on nitrogen‐doped porous carbon nanomaterials by a high‐temperature annealing method. The well‐dispersion...

A smart meta-superconductor Bi(Pb)SrCaCuO (B(P)SCCO) may increase the critical transition temperature (TC) of B(P)SCCO by electroluminescence (EL) energy injection inhomogeneous phases. However, amplitude ?TC (?TC=TC?TC,pure) TC is relatively small. In this study, a with different matrix sizes was designed. Three kinds raw materials particle were used, and series Y2O3:Sm3+, Y2O3, Y2O3:Eu3+, Y2O...
