A Photoelectrochemical Investigation of n- and p-type semi�conducting behaviour of Copper Oxide Films

Siripala W; Kumara K P (Semiconductor Science and Technology, 1989)

Copper(I) oxide films were prepared on copper substrates by exposing them to solutions containing Cu2+ ions, and it was observed that the photoresponse of these films electrodes in a photoelectrochemical cell is both n- ...
Ammonium sulfide surface treatment of electrodeposited p-type cuprous oxide thin films

Jayathileke, K.M.D.C.; Kapaklis, V.; Siripala, W.; Jayanetti, J.K.D.S. (Electronic Materials Letters, 2014)

The effects of ammonium sulfide surface treatment on electrodeposited p-type polycrystalline cuprous oxide (Cu2O) thin films deposited on Ti substrates were studied. The structural and morphological properties of the films ...
Band Edge Shifts of p-type Copper Indium Diselenide Electrodes in Aqueous Electrolytes

Siripala W; Vedel, J.; Lincot, D.; Cahen, D. (Applied Physics Letters, 1993)

Impedance measurements were used to evaluate the relative band edge positions of single crystalp?CuInSe2electrodes in various aqueous electrolytes, by measuring the extrapolated flatband potentials, V fb. We find that V ...
Electrodeposition of n-type Cuprous Oxide Thin Films

Siripala W (Electrochemical Society Meeting, Washington DC, 1, 2002)
Growth and Characterization of Copper Indium Diselenide

Chithrani, B.D.; de Silva, K.T.L.; Jayanetti, J.K.D.S.; Siripala, W. (Proceedings of the Technical Session of Institute of Physics, Sri Lanka, 1996)

CuInSe2 thin films were prepared on Ti plates by electrodeposition from an aqueous solution containing CuCl2, InCl3 and SeO2. The deposition was carried out at -0.5V Vs SCE. X-ray diffraction and Scanning electron microscopy ...
Observation of n-type Photoconductivty in Electrodeposited Copper Oxide Film Electrodes in a Photoelectrochemical cell

Siripala, W.; Jayakody, J.R.P. (Solar Energy Materials, 1986)

Copper oxide films were cathodically deposited on various metal substrates (Cu, Ti and Pt) using a basic solution of CuSO4, and it is found that they produce n-type photoconductivity in a photoelectrochemical cell. The ...
Study of Annealing Effects of Cuprous Oxide Grown by Electrodepostion Technique

Siripala, W.; Perera, L.D.R.D.; de Silva, K.T.L.; Jayanetti, J.K.D.S.; Dharmadasa, I.M. (Solar Energy Materials and Solar Cells, 1996)

Low temperature electrochemical deposition of cuprous oxide from aqueous solutions has been investigated. X-ray diffraction, scanning electron microscopy, optical absorption, and photo-response of liquid/cuprous oxide ...
Sulfidation of electrodeposited microcrystalline/nanocrystalline cuprous oxide thin films for solar energy applications

Jayathileke, K.M.D.C.; Kapaklis, V.; Siripala, W.; Jayanetti, J.K.D.S. (Semiconductor Science and Technology, 2012)

Grain size of polycrystalline semiconductor thin films in solar cells is optimized to enhance the efficiency of solar cells. This paper reports results on an investigation carried out on electrodeposited n-type cuprous ...
Ventilatory function in brass workers of Gadaladeniya Sri Lanka

Jayawardana, P.L.; de Alwis, W.R.; Fernando, M.A. (Oxford University Press, 1997)

A cross sectional study was conducted to determine the respiratory hazards of brass workers. The study group was selected randomly. The control group was selected from the general population matched for age by cluster ...
