TRANSMISSION ELECTRON MICROSCOPY ANALYSIS OF COPPER ZINC SULPHIDE THIN FILMS

In this study, ternary copper zinc sulphide (CZS) thin films were produced using the chemical bath deposition (CBD) technique at 30 0° C. The aim was to investigate the influence o deposition concentrations( 𝑥 = 0.2, 0.4, 0.6, 𝑎𝑛𝑑 0.8), and durations (10, 12, 14, and 16 hours) on the transmission electron microscopy (TEM) characteristics of the prepared CZS thin films. The process involved using an ammonia solution to adjust the pH and triethanolamine (TEA) as a complexing agent. The CBD technique is recognized as a cost-effective and straightforward method, as reported by numerous researchers. The deposited films exhibited crystalline grains that were ellipsoidal in nature and randomly distributed across the substrate, with sizes varying (from 0.2 to 0.6 ) according to the deposition parameters. The influence of deposition time on the morphological characteristics has also been explored. These findings confirm that the CBD-deposited films can be modified from amorphous to polycrystalline for various device applications
