“…Figure 6(b) shows the silver spectrum in 3d state which is located at the binding energies of 368.4 eV and 374.4 eV. The splitting (6 eV) of the silver spectrum is confirmed by the core metal in Ag-3d 5/2 and Ag-3d 3/2 [28]. The figure 6(c) characterize the spectrum of Zn-2p state their binding energies at 1020.7 eV (Zn-2p 3/2 ) and 1023.2 eV (Zn-2p 3/2 ) with 2.5 eV splitting for ZnO and Ag@ZnO nanoparticles.…”

In this study, Ag nanoparticles and Ag@ZnO core-shell nanostructures were prepared using the wet chemical method and these nanostructures were used for Ag@ZnO/p-Si diode fabrication. Structural, morphological, and optical characterization techniques were applied for Ag@ZnO core-shell NPs prepared by using different molarity of precursor ZnCl2 (10 mM, 20 mM, 30 mM) and showed that the effect of increasing precursor amount on these physical properties of nanoparticles is important. For Ag@ZnO, transmission electron microscopy shows an average diameter of Ag nanoparticles was 51.32 nm and Ag@ZnO core-shell nanostructures were found to be between 31 and 92 nm. The UV-visible absorbance also shows significant plasmonic resonance for NPs, with a slight red shift increasing precursor molarity. The peaks are found to be from 412nm to 432nm. This redshift in surface plasmon absorption of Ag@ZnO core-shell structures are consistent with XPS survey. The current-voltage (I-V) characteristic curves of heterojunction diodes were taken in the dark and at room temperature, and it was observed that they showed a rectifying feature. Ideality factor and barrier height values have been found between 2.14 and 3.87, and 0.56 and 0.78, respectively. The results revealed that Ag@ZnO was successfully synthesized and can be used in rectification applications.

“…n this way, the long range to short range displacement transition of the carriers can be found in our investigation with the increase in frequency. [55][56][57] The broadening of the peak with various time constants indicates the dispersion of the relaxation time, and therefore a non-Debye type of relaxation is seen in the material. [58,59] Figure for the separation of the relaxation effects of grains and grain boundaries in materials, we used the benefit of this study is more viable than the Nyquist plot of the impedance investigation (Z' vs Z").…”

This report typically discusses the Voltage-Stability (V-S) of the electrical properties of a new perovskite oxide, Ba0.97La0.02Ti1-xNb4x/5O3 (noted BLT, BLT0.9Nb0.08) ceramics which have been meticulously studied. The ceramics typically exhibited a low rise in the real and imaginary parts of the complex impedance on the application of small field levels (up to 5 V). These accurate data, at a low voltage threshold, properly designate a hole-generation process which becomes active. These values considered using AC impedance spectroscopy, nonetheless, were relatively decreased with increasing Nb concentration, as well as increased by this application of a DC bias. For each sample, the complex impedance plot displayed a single impedance semicircle, identified over the high and low frequencies. The equivalent circuit configuration was typically fitted using the Electrochemical Impedance Spectroscopy (EIS) spectra analyzer. Importantly, the electrical properties of our both compounds deduced from the complex electric modulus show a conduction process due to the short-range mobility of charge carriers. An excellent addition of Niobium to some considerable extent can inhibit the grain growth. Conspicuously, the substitution of Nb5+ ions for Ti4+ on B sites leads to the noticeable increase of a band gap. These findings supplied critical insights into the electric mechanisms in BT-based ceramics.

“…However, considering their low chemical stability, Ag NPs are less studied compared to many other metal NPs. Besides, the size of Ag NPs and deposition methods can both affect the coupling between Ag LSPR and ZnO [32][33][34] . One study investigated the effect of fabricating a plasmonic Schottky junction of TiO2 with Ag/Au in a Kretschman coupling geometry 35 .…”
