WebIn this work we report on the fabrication, characterization and photovoltaic properties of sputter-deposited, thin film heterojunctions combining p-type cupric oxide (CuO) absorber with n-type ZnO. The structural investigation reveals highly crystalline, columnar growth of the layers and confirms that the absorber’s phase is purely CuO, with only negligible … WebPolymer thin-films, however, are often produced via solution processing methods such as spin-coating, where a polymer solution is deposited on a substrate that is rotated at high speed (typically between 1,000 & 10,000 rpm), resulting in the formation of a thin polymer film in a matter of seconds. There then exists a trade-off

WebJun 8, 2024 · Annealing of amorphous polymers is typically performed to reduce the internal stress in a part below the levels achievable during the molding process. However, in semicrystalline polymers the objective of annealing is to establish a level of crystallinity that cannot be practically obtained within the parameters of a normal molding cycle. WebFor thin film (32 nm), relative crystalline density was very weak but the coherence length of crystallites was larger and the orientation of crystallites was even more strongly textured. For thick film, the strong increase of crystalline density takes place through fresh nucleation and reorientation of crystallites already present in the films.
