Figure 1

Comparison of spinodal isotherms in In_1-x-yGa_xAl_yAs. The solid and dashed lines show the spinodal isotherms calculated by using experimental data and those from the DLP model as interaction parameters, respectively.

Figure 2

Comparison between binodal isotherms (solid curves), spinodal isotherms (dashed curves) for InAs_1-x-ySb_xP_y, and experimental data from InAs_1-x-ySb_xP_y grown by MOVPE at 600°C. This figure also shows tie lines (solid lines) after [11].

Figure 3a

Fitting spinodal isotherms of In_1-xGa_xN calculated as a parameter of K to the composition of In_1-xGa_xN grown at 700°C.

Figure 3b

Fitting spinodal isotherms of In_1-xGa_xN calculated as a parameter of K to the composition of In_1-xGa_xN grown at 800°C .

Figure 4

Calculated spinodal and isotherms for In_1-x-yGa_xAl_yN for a constant K of 7 x 10⁶ cal/mol·Å^2.5. The spinodal isotherms at a temperature of 600, 800, and 1000°C are shown with solid curves. The hatched region shows the miscibility gap at 800°C predicted from the spinodal isotherm. The binodal isotherm at a temperature of 800°C and its tie lines are shown with dotted curves and dashed lines, respectively. The transformed lattice constants of binary alloys from a wurtzite structure to a zinc-blende structure and the interaction parameter of three pseudobinary alloys are also expressed.
