In this work, In2O3 thin films were grown on (111) yttria-stabilized zirconia (YSZ) by metal-organic chemical vapor deposition (MOCVD) at different temperature. It is found that samples grown at low temperature showed lower residual stress but higher mosaicity while high growth temperatures could also cause deterioration in crystal quality due to increasing lattice mismatch. To obtain high quality In2O3 film with low residual strain, a 30-nm thick layer grown at 530 °C was introduced as buffer layer, considering both stress relaxation and crystalline mosaicity. By using two-step growth method, a 400 nm-thick, high quality, near-strain-free In2O3 thin film with the full width at half maximum (FWHM) values of (222) diffraction peaks being as narrow as 648 arcsec was successfully obtained.

AbstractQuantum dots (QDs) have been shown to improve the efficiency and optical properties of opto- electronic devices compared to two dimensional quantum wells in the active region. The formation of self-assembled GaN nanostructures on aluminum nitride (AlN) grown on sapphire substrates by Metal Organic Chemical Vapor deposition (MOCVD) was explored. This paper reports on the effect ofin-situactivation in nitrogen atmosphere on MOCVD grown GaN nanostructures. The effect of introducing manganese in these nanostructures was also studied. Optically active nanostructures were successfully obtained. A blue shift is observed in the photoluminescence data with a decrease in nanostructure size.

AbstractPhotoluminescence (PL) spectra were measured at room temperature for GaN quantum wells (QWs) with Al0.8Ga0.2N barriers, which were grown by atmospheric-pressure metal organic chemical vapor deposition (MOCVD). The thickness of the GaN QW layers was systematically varied from one monolayer to four monolayers. We clearly observed a PL peak at a wavelength as short as 247 nm (5.03 eV) from one monolayer-thick QWs. The effective confinement energy is as large as 1.63 eV.
