The Ag-In-Sb-Te active laver transformed into different phases after applyi
ng different initialization powers ranging from 150 mW to 900 mW. With an i
nitialization power of 250 mW, the rhombohedral Sb crystalline phase was fo
rmed. For higher initialization powers, i.e.. 350 mW or 450 mW. the AgSbTe2
crystalline phase and the newly proposed fee Sb crystalline phase started
to form. For initialization powers higher than or equal to 550 mW, no rhomb
ohedral Sb phase was observed.
