Исследование влияния кислорода на параметры ближнего порядка структур Ge2Sb2Te5

Abstract

The principle of the transition between crystalline and amorphous phases of Ge2Sb2Te5 underlies the functioning of common use electronic devices such as CDs and DVDs. The most important feature of Ge2Sb2Te5 chalcogenide alloy determined phase switching parameters is local structure. In the following paper the Ge2Sb2Te5 local structure investigation based on the Xray Absorption Near Edge Structure and Extended X-Ray Absorption Fine Structure measurements was performed.
