“…A number of methods have been reported earlier for the deposition of thin films. Such methods are electrodeposition (Murali and Austine 2009), molecular beam epitaxy (MBE) (Schreder et al 2000), electron beam pumping (Trager-Cowan et al 1996), vacuum evaporation (Kishore et al 2005), pulse plating (Murali and Balasubramanian 2010), chemical bath deposition (CBD) (Sutrave et al 2000;Singh et al 2011Singh et al , 2013Singh et al , 2015Singh et al , 2014Thool et al 2014) etc. Among the above mentioned techniques, CBD has been attracted considerable attention as due to its simplicity, cost effectiveness, convenience and capability for depositing smooth, homogenous and good quality thin films at large area.…”
