Recent Findings in Non-Crystalline Solids Described by Researchers from Indian Institute of Science

May 6, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Non-Crystalline Solids have been published. According to news originating from Bangalore, India, by VerticalNews correspondents, research stated, "Micro-Raman studies are conducted on as-quenched and annealed Ge15Te80 -_xIn5Agx glasses to probe the structural network and its evolution with composition. These studies reveal the presence of tetrahedral GeTe4 structural units in as-quenched samples."

Our news journalists obtained a quote from the research from the Indian Institute of Science, "Specific signatures of the intermediate phase (IP) are observed in the composition dependence of Raman frequencies and corresponding intensities of different modes in the composition range, 8

According to the news editors, the research concluded: "Based on our present and earlier studies, we propose the occurrence of three thresholds in Ge15Te80 - xIn5Agx glasses, namely percolation of rigidity, percolation of stress and the onset of chemical phase separation on a nanoscale at 8%, 16% and 20% of silver concentration respectively."
