Synthesis And Studied Structural and Morphological Properties of 1-Dimensional Zno-Ag2O-Ag Nanowire

1-dimensional zinc oxide (ZnO) - silver oxide (Ag2O) – silver (Ag) nanowire was prepared using a simple and inexpensive bottom-up chemical method. X-ray diffraction (XRD) results showed the presence of diffraction peaks of ZnO and Ag2O with hexagonal wurtzite phase of ZnO. Energy Dispersive X-ray (EDX) results showed the presence of energy peaks of Zinc (Zn), Silver (Ag), and Oxygen (O) elements. Filed Emission Scanning Electron Microscopy (FE-SEM) results showed that the surface morphology is nanowire (1-dimensional structure) with shapes similar to hedgehog spines and have small nanoscale diameters. The present work represents a promising step in the preparation of a 1-dimensional nanowire.

The influence of single layer MoS2 flake on the propagated surface plasmons of silver nanowire

We demonstrate the enhancement of both excitation and transmission efficiency of the propagated surface plasmon (SP) of Ag nanowire (Ag NW) in hybrid Ag-MoS2 structure by contrasting the SP propagation of the same Ag NW on different substrates including silicon substrate, monolayer MoS2, or partially overlapping the Ag NW on MoS2 flake. The simulation results indicate that with the assistance of MoS2, the leaky radiation of the hybrid plasmonic modes of the H1 and H2 can be prominently suppressed by the high refractive index dielectric layer of the MoS2, which provides an optical barrier blocking the leaky radiation, resulting in the reduced propagation loss. Our work provides a feasible and effective method to enhance the SP propagation length.
