Theoretical Calculation of Miscibility Gap for MgxZn1-XO Alloys
In this paper, a theoretical calculation of the miscibility gap taking modified interaction parameter and mismatch strain into account are performed for the MgxZn1-xO ternary compound system using the modified strictly regular solution model. The calculated results shows that the MgxZn1-xO alloys are metastable at the temperatures commonly used for crystal growth and the miscibility gap shifts remarkably into the areas of higher Mg concentration and higher temperature because of the interaction parameter modifiability and strain effect. The strain relaxation is discussed synchronously, with the increasing of the strain relaxation, the MgO segregation boundary expands to a bend band region.
