May I get some advice to increase the crystallinity of thin films? I have prepared triazine-based films at room temperature with the help of a photocatalyst but crystallinity has been a problem for one month. I have already tried some ways e.g. altering the rate of reaction and changing the quantity of monomers and substrate but failed to achieve the goal!
The naive idea is a banal increase or decrease in temperature, since the glass transition depends primarily on temperature. How much the photocatalyst affects the crystallinity is unknown to me.
Hello Khalid
I nothing understand of your special material but I have to do experimental work at crystalline layers.
In the most cases the layers are deposited on substrates. It is important to select a substrate with comparable crystal structure and similar lattice constant.
Very often, the crystal must be annealed after layer deposition. This means, heating in vacuum up to 10% below the boiling point. This reduces lattice defects.
