Characterization of Cu2O thin films with addition of additive prepared by sol-gel spin coating process
Dewi Suriani, Che Halin, Dr.; Ibrahim, Abu Talib; A. R., Daud; Muhammad Azmi, A. Hamid (Universiti Putra Malaysia, 2010)Cuprous Oxide (Cu2O) thin films were formed onto indium tin oxide (ITO) coated glass substrate by sol-gel spin coating technique using different additives namely polyethylene glycol and ethylene glycol. It was found that ... -
Effect of annealing atmosphere on the morphology of copper oxide thin films deposited on TiO₂ substrates prepared by sol-gel process
Dewi Suriyani, Che Halin; Ibrahim, Abu Talib; Abdul Razak, Daud; Muhammad Azmi, Abd Hamid (Trans Tech Publications, 2014)Copper oxide films were prepared via sol-gel like spin coating starting from methanolic solutions of cupric chloride onto the TiO₂ substrates. Films were obtained by spin coating under room conditions (temperature, 25-30 ... -
Mechanism of current transport for a photoelectrochemical cells of ITO/Cu2O/PVC-LiClO4/graphite
Dewi Suriyani, Che Halin, Dr.; Haiza, Haroon; Ibrahim, Abu Talib, Prof. Dr.; Abdul Razak, Daud, Prof. Dr.; Muhammad Azmi, Abd Hamid, Assoc. Prof. Dr. (Trans Tech Publications, 2013)This paper deals with the current transport mechanism of solid state photoelectrochemical cells of ITO/Cu2O/PVC-LiClO4/graphite as well as the physical properties of a component of a device affecting its performance.

Microstructures study on cuprous oxide thin films deposited on different substrates by using sol-gel technique
Dewi Suriyani, Che Halin; Ibrahim, Abu Talib; Haiza, Haroon; Abdul Razak, Daud; Muhammad Azmi, Abd Hamid (Scientific.Net/Trans Tech Publications, 2012-12)Cuprous oxide (Cu₂O) thin films were formed onto three different substrates such as indium tin oxide (ITO) coated glass, titanium oxide (TiO₂) and n-Si substrates by sol-gel spin coating technique. It was found that the ... -
Overview of pathogenic micro-organisms destruction in contaminated water by oxide photocatalysis
Noor Azira, Mohd Noor; Muhammad Asri, Idris, Dr.; Dewi Suriyani, Che Halin, Dr.; Mohd Nazree, Derman, Dr.; Mohd Arif Anuar, Mohd Salleh (Trans Tech Publications, 2013)The titanium dioxide (TiO2) is a semiconductor oxide photocatalys, which is chemically and biologically inert but exhibits excellent photolytic activity in the ultraviolet (UV) region. Progress in photocatalytic water ... -
Preparation of photoelectrochemical cell of ITO/Cu2O/PVC-LiClO4/graphite using Cu2O films as an active layer
Dewi Suriyani, Che Halin; Haiza, Haroon; Ibrahim, Abu Talib; Abdul Razak, Daud; Muhammad Azmi, Abd Hamid (Trans Tech Publications, 2014-02)Cuprous oxide (Cu2O) thin films were successfully grown on indium tin oxide (ITO) coated glass by sol-gel spin coating using diethanolamine (DEA) as a solubility agent. The films were annealed at 350 °C in 5% H2 + 95% N2 ...
