Journal ArticleDOI
Enhanced electrical properties of antimony doped tin oxide thin films deposited via aerosol assisted chemical vapour deposition
Sapna D. Ponja,Benjamin A. D. Williamson,Sanjayan Sathasivam,David O. Scanlon,Ivan P. Parkin,Claire J. Carmalt +5 more
TL;DR: In this article, a novel and scalable synthetic route to ATO thin films that shows excellent electrical properties was presented, which is an excellent candidate but is limited by its opto-electrical properties.
Journal ArticleDOI
Highly conductive and transparent gallium doped zinc oxide thin films via chemical vapor deposition.
TL;DR: Ga was achieved due to using oxygen poor growth conditions enabled by diethylzinc and triethylgallium precursors, and was seen as a potential substitute to the ubiquitous and expensive Sn doped In 2 O 3 as a transparent electrode in optoelectronic devices.
Journal ArticleDOI
Aerosol assisted chemical vapour deposition of hydrophobic TiO2–SnO2 composite film with novel microstructure and enhanced photocatalytic activity
Sapna D. Ponja,Sanjayan Sathasivam,Nicholas Chadwick,Andreas Kafizas,Salem M. Bawaked,Abdullah Y. Obaid,Shaeel A. Al-Thabaiti,Sulaiman N. Basahel,Ivan P. Parkin,Claire J. Carmalt +9 more
TL;DR: Aerosol assisted chemical vapour deposition (AACVD) was used to synthesize a TiO2-SnO2 composite film onto a glass substrate in this paper.
Journal ArticleDOI
Transparent conductive aluminium and fluorine co-doped zinc oxide films via aerosol assisted chemical vapour deposition
TL;DR: Aerosol assisted chemical vapour deposition (AACVD) was employed to synthesize highly transparent and conductive ZnO, fluorine or aluminium doped and aluminium-fluorine co-doped ZnOs thin films on glass substrates at 450 °C as mentioned in this paper.
Journal ArticleDOI
Synthesis and material characterization of amorphous and crystalline (α-) Al2O3 via aerosol assisted chemical vapour deposition
TL;DR: In this article, the facile synthesis of Al2O3 in the amorphous and corundum phase on both glass and quartz substrates is reported, carried out via aerosol assisted chemical vapour deposition using Al(acac)3 and methanol.
