Scanning electron microscopy electrodeposited

Chong et al. [742] have described a multielement analysis of multicomponent metallic electrode deposits, based on scanning electron microscopy with energy dispersive X-ray fluorescence detection, followed by dissolution and ICP-MS detection. Application of the method is described for determination of trace elements in seawater, including the above elements. These elements are simultaneously electrodeposited onto a niobium-wire working electrode at -1.40 V relative to an Ag/AgCl reference electrode, and subjected to energy dispersive X-ray fluorescence spectroscopy analysis. Internal standardisation... 

The novel SERS-active substrates were prepared by electrodeposition of Ag nanoparticles in the MWCNTs-based nanocomposites. The formation of Ag-MWCNTs nanocomposite was characterized by scanning electron microscopy and energy dispersive X-ray spectroscopy. The application of the Ag-MWCNTs nanocomposite in SERS was investigated by using rhodamine 6G (R6G). The present methodology demonstrates that the Ag-MWCNTs nanocomposite is suitable for SERS sensor. 

To study in detail the process of the nickel electrodeposition into porous silicon, the electrodeposition was stopped at various process stages, namely, after 10, 20, and 30 min, and the cross-sections of the samples formed were examined by the scanning electron microscopy. The A, B, and C points in the potential curve (Fig. 1) correspond to these stages. 

Before specifically dealing with coherent x-ray imaging, its foundations, and its advantages, we note that alternate experimental solutions were used to tackle these problems. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) probe the surface morphology and the overall microstructure of metal electrodeposits. However, they do not work in real time they are used to analyze the final products after the end of the growth. 

Thin films of Cu, Co and Ni on Si were prepared from different aqueous electrolytes containing sulfates of the respective metals as well as some supporting electrolyte/additive. Voltammetry and current transients were used to analyze the electrochemical aspects of the deposition. The electrodeposited layers were investigated by scanning electron microscopy (SEM), Rutherford backscattering (RBS), magnetooptical Kerr effect (MOKE), X-ray diffractometry (XRD) as well as by electrical measurements.

The electrodeposits were examined by scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), x-ray diffraction (XRD), transmission electron microscopy (TEM) and x-ray photoelectron spectroscopy (XPS). 

Typical spongy electrodeposits are formed during zinc and cadmium electrodeposition at low overpotentials [7,74]. Scanning electron microscopy images of zinc deposited at an overpotential of 20 mV onto a copper electrode from an alkaline zincate solution are shown in Fig. 1.27.

This paper describes ongoing studies of the electrodeposition thin films of the compound semiconductors CdTe and InAs, using the method of electrochemical atomic layer epitaxy (ALE). Surface limited electrochemical reactions are used to form the individual atomic layers of the component elements. An automated electrochemical flow deposition system is used to form the atomic layers in a cycle. Studies of the conditions needed to optimize the deposition processes are underway. The deposits were characterized using X-ray diffraction, scanning probe microscopy, electron probe microanalysis and optical/infrared absorption spectroscopy.
