Relaxing the Conductivity/Transparency Trade-Off in MOCVD ZnO Thin Films by Hydrogen Plasma
Increasing the conductivity of polycrystalline zinc oxide fi lms without impacting the transparency is a key aspect in the race to fi nd affordable and high quality material as replacement of indium-containing oxides. Usually, ZnO fi lm conductivity is provided by a high doping and electron concentration, detrimental to transparency, because of free carrier absorption. Here we show that hydroge...
متن کاملHigh Quality YBa2Cu3O7-x Superconducting Thin Films Grown by MOCVD
YBCO thin films have been grown by Metal Organic Chemical Vapour Deposition in ;I cold wall type reactor. The 0-diketonates of yttrium, barium and copper are used as precursors. Filrna have bcen deposited on (001 I MgO and (012) LaA103 single crystalline substrates. The morphology is very dependant on thc gas p h a x composition. Different oxygen partial pressures have been investigated. An inc...
متن کاملCharacterization of ZnO Thin Films
ZnO is a strategic material for various photonic applications. We present our results on characterization of thin films of ZnO grown by sol-gel spin and RF sputtering methods. The characterization techniques involved ellipsometry, scanning electron microscopy with energy dispersive analysis, X-ray diffraction and scanning tunneling microscopy. Microstructural characterization of the films using...
متن کاملHREM Characterization of Interfaces in Thin MOCVD Superconducting Films
This paper is concerned with high-T, superconducting compounds produced by metal-organic chemical vapour deposition. The nanostructure of different types of interfaces yttria stabilized zirconia buffer / (l-102)-sapphire substrate, YBazCu307-, film / Y2O3 precipitates as well as YBa2Cu307-, film / (001)-NdGa03, -SrTiO3, and -MgO substrates has been investigated by high resolution electron micro...
متن کاملMOCVD growth of non-epitaxial and epitaxial ZnS thin films
Thin films of ZnS have been deposited by MOCVD on both BaTa206/ITO/glass and Si substrates. Diethylzinc (DEZn) and H2S are used for deposition on substrates heated to the 250-400°C temperature range. The microstructure and properties of ZnS films were studied by X-ray diffractometry (XRD), ultraviolet/visible spectrophotometry (UVS) and scanning electron microscopy (SEM). Films prepared on BaTa...
