We have investigated growth of InAs on Si substrates by metal organic chemical vapor deposition. The main investigation is the effect of incorporating more nucleation layers into the growth process. The addition of more nucleation layers clearly correlates with the surface morphology and quality of the InAs layer. Morphological and structural characterizations prove that a perfect quality InAs layer is achieved by incorporating five nucleation layers.

Organic Chemical Vapor Deposition

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.

AbstractDeposition of thin films of Co- and Mn- oxides as well as of their mixtures with ZrO2 have been carried out by MOCVD using Co(C5H5)2, Mn(C5F6HO2)2(THF)2and (C5Hs)2Zr(CH3)2as precursors. XRD and XPS analyses of the obtained deposits are reported. Introduction of water vapor into the reactor chamber during the flow of the precursors improved their decomposition efficiency and the quality of the films.
