Abstract
High quality InAs 0.85Sb 0.15 film has been successfully grown on (1 0 0) InAs substrate by liquid phase epitaxy using InAs 0.93Sb 0.07 buffer layer. The microstructure and morphologies of the film were characterized by high-resolution X-ray diffraction, scanning electronic microscopy, optical microscopy, atomic force microscopy, and high-resolution transmission electron microscopy. These results show that the high quality film with mirror-like surface was obtained. The optical properties were investigated by photoluminescence and the Raman spectra. The peak position of photoluminescence spectrum for the film is about 0.35 eV at 77 K. In addition to the reported single-mode phonon behavior, the local vibration mode associated with Sb atoms was also observed in the Raman spectra.
