Self-assembling of 1O4Mg clusters in ZnTe doped with Mg and O

Phase transitions in ZnTe co‐doped with Mg and oxygen

“…[1][2][3][4] differ from the well-known homogeneous, decomposed alloys and alloys with a superstructure. In these already studied alloys the presence of clusters of various sizes, compositions and forms is more thermodynamically profitable than that of uniform clusters.…”

“…Thus, two origins can initiate the formation of uniform tetrahedral clusters. Both of these origins should cause SA of 1O4Mg clusters in ZnS and ZnTe co-doped with Mg and oxygen in the ultra dilute oxygen impurity limit [3,4]. All these papers present the studies of the conditions when the free energy of the alloy with the clusters containing all minority impurity atoms become smaller than that of the random alloy.…”

“…The phenomenon of SA reported in Refs. [1][2][3][4] paves the way to it. However, thermodynamically profitable conditions of SA when all or almost all highly mismatched impurity atoms are in uniform clusters should be studied.…”
