Amorphous and nanophase microstructures of bulk Se-based chalcogenide alloys

The composition-dependent microstructural morphology variations of Se 89Zn 2Te 5In 4 and Se 87Zn 2Te 5In 6 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 Se 89Zn 2Te 5In 4 alloy belongs to pure glassy state, while the Se 87Zn 2Te 5In 6 alloy is with nanophase structure. © 2012 Tianjin University of Technology and Springer-Verlag Berlin Heidelberg.
