New Findings from Faculty of Sciences Update Understanding of Optoelectronics

February 12, 2014



By a News Reporter-Staff News Editor at Electronics Newsweekly -- Current study results on Optoelectronics have been published. According to news originating from Agadir, Morocco, by VerticalNews correspondents, research stated, "The phase diagram of the Sn-Y and thermodynamic system has been critically assessed by means of CALPHAD technique."

Our news journalists obtained a quote from the research from the Faculty of Sciences, "The solution phases (liquid, hcp and bcc) are modeled with the Redlich-Kister equation, and the intermetallic compounds (Sn4Y5, Sn10Y11, Sn2Y, Sn5Y2 and Sn3Y) are treated as stoichiometric compounds. The Sn3Y5 sub-stoichiometric intermetallic compound, which have a homogeneity range, were treated with the formula (Sn)(0.375)(Sn,Y%)(0.625) by a two-sublattice model with Sn on the first sublattice and Sn and Yon the second one."

According to the news editors, the research concluded: "The calculated phase diagram and the thermodynamic properties of the system are in satisfactory agreement with the majority of the experimental data."
