Abstract: In this study Al-5 (Vol) % SiCp nanocomposite powder has been successfully synthesized by high-energy planetary milling of Al and SiC powders for a period of 25 h at a ball-to-powder ratio of 15:1. The changes of the lattice strain, the crystallite size of the matrix phase, and the nanocomposite powder microstructure with time have been investigated by X-ray diffraction (XRD), X-ray m...

The polarization response of a coplanar electrochemical capacitor covered with an ionic liquid as the electrolyte has been examined using combination two powerful analytic techniques, X-ray photoelectron spectroscopy (XPS) and scanning electron microcopy (SEM). Spatiotemporal distribution surface potential, upon DC or AC (square wave) biasing, monitored via chemical element binding energy shift...

Compound semiconductor devices, as typified by laser diodes, photo diodes, and high electron mobility transistors, are used for optical communication systems, satellite communications, and cellular base stations to meet a growing demand for large-capacity and high-speed communication systems that play a key role in the infrastructure of modern society. The properties and reliability of semicond...

The high pressure SEM (HPSEM) is an important tool for materials characterisation. The presence of a gaseous atmosphere inside the specimen chamber permits to limit the charging effect and to obtain image with specific electron detector. The electron beam scattering due to the introduction of the gas within the specimen chamber of the HP-SEM influences the image quality and the microanalysis re...
