Lattice Location Studies of the Amphoteric Nature of Implanted Mg in GaN

LATTICE LOCATION AND OPTICAL ACTIVATION OF RARE EARTH IMPLANTED GaN

This paper reviews the current knowledge on rare earths (REs) implanted into GaN with a special focus on their lattice location and on the optical activation by means of thermal annealing. While emission channeling experiments have given information on the lattice location of rare earths following low-dose (≈10 cm) implantation, both in the asimplanted state and after annealing up to 900°C, the...

Lattice location of implanted Ag in Si

The lattice location of implanted silver in Si was studied by means of the emission channeling technique. Following 60 keV room temperature implantation of radioactive Ag at a dose of 2-3×10 cm, we identify around 30% of Ag on near-substitutional sites (≈0.45 Å from ideal S-sites). Upon annealing at 200-300°C, the fraction on near-S sites reaches a maximum around 60-80%. For higher annealing te...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
