Structure–property relationship of nanocrystalline tin dioxide thin films grown on (1̄012) sapphire

Tin Oxide Thin Films Grown on the (1̄012) Sapphire Substrate

Tin oxide thin films were deposited on the R-cut sapphire substrate by the electron-beam evaporation of a ceramic SnO2 source. X-ray diffraction and transmission electron microscopy studies revealed that the films deposited at lower temperatures were amorphous while those grown at temperatures above 350◦C consisted of the α-SnO phase with the PbO type structure. Epitaxial α-SnO films on the R-c...

Titanium dioxide nanocrystalline bactericidal thin films grown by sol-gel technique

Titanium dioxide thin films were grown by sol–gel technique in order to obtain films to be used in photocatalytic reactions. We present results on the structural and optical characterization measured for series of films in which number of layers and sintering temperature were changed. Using X-ray diffraction we have characterized the crystalline phase in the films depending on the growth condit...

Nanocrystalline magnetite thin films grown by dual ion-beam sputtering

Oxidation and phase transitions of epitaxial tin oxide thin films on „1̄012... sapphire

We studied the structural behavior and electrical transport properties of epitaxial a-SnO thin films grown on the (1̄012) a-Al2O3 ~sapphire! substrate. Hall effect measurements revealed that the epitaxial as-deposited SnO film is a p-type semiconductor. In situ x-ray diffraction studies show that the a-SnO phase is metastable and will transform into SnO2 with the rutile type structure when annea...

Metal organic chemical vapor deposition and investigation of ZnO thin films grown on sapphire

A new type of large area metal organic chemical vapor deposition (MOCVD) system for the growth of high quality and large size ZnO materials is introduced. Materials properties of the un-doped, nand p-doped ZnO epi-films grown on sapphire substrates by this MOCVD system are studied by various techniques, including high resolution X-ray diffraction (XRD), UV–Visible optical transmission (OT), pho...
