PHASE DIAGRAM CALCULATION OF GaN1-xPx TERNARY ALLOYS WITH A CONTENT GRADUAL CHANGE MODEL

摘要：

There exists a large miscibility gap in GaN1-xPx ternary system,which results in that the phase separation occurs easily and hence limits the development of the material system.So it is very important to clarify the unstable and stable-mixing regions of this material system.Usually,a theoretical calculation of the solid interaction parameter and the miscibility gap are performed tbr the GaN1-xPx ternary alloy system using the delta-lattice-parameter model and the strictly regular solution model,respectively.In the reference 1,the effects of mismatch strain and elastic parameter on the miscibility are taken into account in order to predict the immiscibility region of GaN1-xPx more reliable.In this paper,a new content gradual change model (CGCM) is used to calculate phase diagram and predict the immiscibility region of GaN1-xPx.
