Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the deposition principle?Solution-based thin-film deposition driven by heterogeneous nucleation on a substrate
2. What is the operational parameters?Typically operates at low temperatures (<100 °C) and atmospheric pressure
3. How does chemical bath deposition make a film?Ions in the liquid stick to the surface and react, slowly building up a solid layer, while the liquid stays mostly clear.
4. Why is chemical bath deposition cheaper and easier than other methods?It works at normal pressure and low temperatures, so it doesn't need fancy vacuum machines, making it cheaper and easier to use.

Heterogeneous Nucleation: The formation of a new solid phase on the surface of a different solid material (the substrate).
Complexing Agent: A chemical substance that binds to metal ions, controlling their release and reaction rate in solution.
Stoichiometry: The quantitative relationship between reactants and products in a chemical reaction, referring to the exact proportions of elements in a compound.
