Crystallographic Orientations

It is well known that the presence of space charges in an insulator is correlated with electric breakdown. Many studies have been carried out on the experimental characterization of space charges and on phenomenological models of trapping and detrapping. In this paper, we outline the dependence on crystallographic orientations of the charge-trapping phenomenon in polished MgO. The charging phenomenon was characterized during and after electron injection by using a scanning electron microscope (SEM). It was shown that the trapping ability depends on the dislocation network of different crystallographic orientations. PACS No.: 72.20Jv

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.

For a better understanding of the physical mechanisms involved in insulators submitted to electron irradiation inside a scanning electron microscope, it is important to investigate charge trapping and detrapping. The commonly used technique to deduce the trapping ability and the motion process of electric charges is based on two complementary experimental methods: the scanning electron microscope mirror effect (SEMME) and the induced current measurement (ICM). In this paper, our study is devoted to the influence of temperature on the behavior of porcelain materials during electron injection time. To evaluate the geometry of the trapped charge distribution, a detailed analysis using the mirror image formation and its evolution is developed.

The purpose of this paper is to study the morphological characterization of aluminum interdigitated electrodes (IDE) of different gap sizes on silicon substrate. The electrodes were fabricated using standard photolithography process and were done so with sizes of 12 μm, 10 μm and 7 μm. The electrodes were morphologically characterized using scanning electron microscope (SEM) and high-powered microscope (HPM).Keywords: morphological, interdigitated electrodes, aluminum
