M. alkmatys@yahoo.com CdS Sol-gel spin coating Grain size and band gap The 2nd International Malaysia-Ireland Joint Symposium on Engineering, Science and Business 2012 (IMiEJS2012) jointly organized by Universiti Malaysia Perlis and Athlone Institute of Technology in collaboration with The Ministry of Higher Education (MOHE) Malaysia, Education Malaysia and Malaysia Postgraduates Student Association Ireland (MyPSI), 18th - 19th June 2012 at Putra World Trade Center (PWTC), Kuala Lumpur, Malaysia. Cadmium sulfide (CdS) thin films of nanostructure were prepared with Cd:S (1.2 to 0.05 mol/L) and different spin coating speed (1000 and 5000 rpm) using sol-gel spin coating technique. Structural, morphological and analytical studies were investigated by x-ray diffraction XRD, scanning electron microscopy (SEM), fourier transform infrared (FTIR) and UV-VIS Spectrophotometer. It is found that the average grain size of CdS in the thin films is 1.35 to 2.66 nm for 1000 and 5000 rpm. The band gap was also calculated from the equation relating absorption coefficient to wavelength. The band gap indicates the film is transmitting within the visible range and the band gaps changes because of the grain size of the CdS in the films. The physical conditions were kept identically while growing all the samples. The effect of grain size on the semiconductor properties is under consideration 2013-10-30T14:39:25Z 2013-10-30T14:39:25Z 2012-06-18 Working Paper p. 86-91 978-967-5760-11-2 http://hdl.handle.net/123456789/29373 en Proceedings of The 2nd International Malaysia-Ireland Joint Symposium on Engineering, Science and Business 2012 (IMiEJS2012); Universiti Malaysia Perlis (UniMAP)
