Abstract
Compositional inhomogeneity in a GaInN ternary alloy layer is investig ated. A theoretical estimation of the interaction parameter based on t he delta lattice parameter suggests that the immiscibility of InN in a nitride alloy is very strong. We investigate the compositional splitt ing and the existence of InN inclusion in the GaInN epilayer grown on sapphire (0001) substrates. Thc mechanism of compositional inhomogenei ty is discussed.
