| Abstract: | The temperature phase stability of GaxIn1−xPyAs1−y solid solution has been analyzed. A simple solution theory with the temperature-independent interaction parameters in solid and liquid phases has been used. The absence of miscibility gaps for all the compositions of the solid solution, lattice-matched to InP at a growth temperature of 640°C, has been demonstrated both theoretically and experimentally. The influence of the elastic deformations on the GaxIn1−xPyAs1−y (λg = 1.4 μm) solid solution parameters has been observed assuming the model of the layer coherent conjugation in heterostructures. |
