Factors affecting the size of ZnO thin films (by spray pyrolysis)

[ralden]

Good day guys, aside solution concentration and depositing time, what are the factors affecting the size of the ZnO thin films deposited by spray pyrolysis. Also please include the articles or links for citation thanks!

The size of ZnO thin films deposited by spray pyrolysis is affected by several factors, such as temperature, deposition rate, and the type of substrate used. Temperature: Higher temperatures can lead to larger grain sizes due to increased diffusion and higher growth rates. However, excessively high temperatures can cause damage to the substrate or decrease the crystallinity of the film.Deposition rate: Higher deposition rates increase the growth rate, but too high a rate can cause decreased crystallinity.Substrate type: The type of substrate can affect the film quality due to its surface energy. For example, a hydrophilic substrate may lead to a more uniform film as compared to a hydrophobic substrate.Sources: 1. S. M. Nanda, L. H. C. Fernandes, M. J. F. Gomes, A. G. D. Silva, and A. P.
