Abhay Kumar Singh.Amorphous and nanophase microstructures of bulk Se-based chalcogenide alloys[J].Optoelectronics Letters,2012,8(3):165-167 Amorphous and nanophase microstructures of bulk Se-based chalcogenide alloys Author Name Affiliation Abhay Kumar Singh  Department of Physics, Indian Institute of Science, Bangalore 560012, India  Abstract:       The composition-dependent microstructural morphology variations of Se89Zn2Te5In4 and Se87Zn2Te5In6 chalcogenide alloys are investigated. Glassy and nanophase surfaces and structural morphologies of these alloys have been described with help of scanning electron microscope (SEM) and transmission electron microscope (TEM), and their elemental concentrations are confirmed from the energy dispersive X-ray spectroscopy (EDX). Experimental results demonstrate that the microstructure of Se89Zn2Te5In4 alloy belongs to pure glassy state, while the Se87Zn2Te5In6 alloy is with nanophase structure.
