Fabrication of ZnO nanowires (NWs) by thermal oxidation method has been studied in this work. The ZnO NWs have been grown by oxidation of Zn metal foil under oxygen environment for two typical oxidation durations. We have investigated the behavior of the as-grown ZnO NWs with the change in oxidation duration at particular temperature. The changes in surface morphology and chemical composition with the variation of oxidation duration have been analyzed by scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS) respectively. From EDS spectra, it is confirmed that Zn metal has completely oxidized into ZnO for higher oxidation duration. In this work, the optimized duration of oxidation for growth of ZnO NWs is found to be ~60 minutes at particular temperature of 600oC. The present method provides a possible mechanism for the growth of ZnO NWs on the p-Si substrates.

In this study, CA fibers were fabricated using electrospinning technique with the mixture of acetic acid/acetone as the solvent system with the ratio of 3:1. The morphological structure of the fibers obtained was observed using scanning electron microscope (SEM). The SEM results showed that 10% of CA produced beads only, 12% of CA produced spindle beads with few fibers, 13% of CA produced fibers with few beads and 14% w/v concentration of CA produced continuous and smooth ribbon-like fibers with average diameter of 199.23nm.

Solid state materials in the form of thin films have found increasing structural and electronic applications. Among the multitude of thin film deposition techniques, the radio frequency induced plasma sputtering has gained considerable utilization in recent years through advances in equipment design and process improvement, as well as the discovery of the versatility of the process to control film properties. In our laboratory we have used the scanning electron microscope extensively in the direct and indirect characterization of sputtered films for correlation with their physical and electrical properties.Scanning electron microscopy is a powerful tool for the examination of surfaces of solids and for the failure analysis of structural components and microelectronic devices.

Abstract The scanning electron microscope (SEM) based nanoprobing technique has established itself as an indispensable failure analysis (FA) technique as technology nodes continue to shrink according to Moore's Law. Although it has its share of disadvantages, SEM-based nanoprobing is often preferred because of its advantages over other FA techniques such as focused ion beam in fault isolation. This paper presents the effectiveness of the nanoprobing technique in isolating nanoscale defects in three different cases in sub-100 nm devices: soft-fail defect caused by asymmetrical nickel silicide (NiSi) formation, hard-fail defect caused by abnormal NiSi formation leading to contact-poly short, and isolation of resistive contact in a large electrical test structure. Results suggest that the SEM based nanoprobing technique is particularly useful in identifying causes of soft-fails and plays a very important role in investigating the cause of hard-fails and improving device yield.

Ultrafine fibers were electrospun from polyacrylonitrile (PAN)/N,N-dimethyl formamide (DMF) solution as a precursor of carbon nanofibers. The effects of solution concentration, applied voltage and flow rate on preparation and morphologies of electrospun PAN fibers were investigated. Morphologies of the green fibers, stabilized fibers and carbonized fibers were compared by scanning electron microscope (SEM). The diameter of PAN nanofibers is about 450nm and the distribution of diameter is well-proportioned. Characterization of the elements changes of fibers were performed by X-ray photoelectron spectroscopy (XPS).
