Ultrasonic and structural characterization of Ge2Sb2Te6 - GST Phase-change materials for memory applications

This study explores ultrasonic non-destructive testing (NDT) to determine the elastic properties of Ge _2 Sb _2 Te _6 - GST, a phase-change material widely used in data storage technologies. Ultrasonic measurements were conducted to determine both longitudinal and transverse velocities. Mechanical p...
