Abstract
High resolution x-ray diffraction and transmission electron microscopy (TEM) were used to study the strain behavior in InAlAs oxides grown on In0.52 Al0.48 As epilayer lattice matched to InP (100) substrates by wet thermal oxidation technique. The relaxed strain morphology has been observed between the InAlAs oxides and lattice matched InAlAs epilayer to InP substrates with the optimization of process temperature, rate of oxidation, and time. Almost strain-free InAlAs oxide layer with high crystallographic quality was obtained on InAlAs epilayer, which is similar to that of lattice matched InAlAs epilayer grown on InP substrate.
