Effect of oxygen partial pressure on the microstructural and physical properties on nanocrystalline tin oxide films grown by plasma oxidation after thermal deposition from pure Sn targets

Güler, Mehmet Oğuz; Gültekin, Deniz; Uysal, Mehmet; Alp, Ahmet; Akbulut, Hatem; Uysal, Mehmet (PERGAMON-ELSEVIER SCIENCE LTD, 2008)

In this work, microstructural and physical properties were studied in the tin oxide films deposited by thermal evaporation of Sn films on stainless steel substrates followed by in situ D.C. plasma oxidation at 200 degrees ...
Production of Sn/SnO2/MWCNT Composites by Plasma Oxidation After Thermal Evaporation from Pure Sn Targets Onto Buckypapers

Gültekin, Deniz; Akbulut, Hatem (AMER SCIENTIFIC PUBLISHERS, 2012)

In this study, tin/tinoxide/multi oxide/multi walled carbon nano tube (Sn/SnO2/MWCNT) composites were produced by thermal evaporation and then subsequent plasma oxidation. Buckypapers having controlled porosity were prepared ...
Raman Studies of ZnO Products Synthesized by Solution Based Methods

Gültekin, Deniz; Akbulut, Hatem (POLISH ACAD SCIENCES INST PHYSICS, 2016)

In this study, nanostructured ZnO thin film coatings produced by sol-gel method have been examined and characterized. ZnO thin film coatings synthesized by the preparation of ZnO sols in the liquid phase from homogeneous ...
Synthesis of ZnO, SnO2 Nanoparticles and Preparation of ZnO-SnO2 Nanocomposites

Gültekin, Deniz; Güler, Mehmet Oğuz; Akbulut, Hatem (AMER SCIENTIFIC PUBLISHERS, 2012)

This article reports the preparation of ZnO-SnO2 nanocomposites from ZnO and SnO2 nanoparticles produced by homogenous precipitation route. Zinc acetate dihydrate (Zn(CH3COO)(2)center dot 2H(2)O) and tin(II) chloride ...
