WebJul 17, 2013 · The top layer was assumed to be 50% void and 50% AlN, whereas, the lower layer was assumed as bulk (100% AlN). This is a well established technique in ellipsometry. The optical property of AlN film was generated using the Tauc-Lorentz model. This model was used due to the poor crystalline nature of the deposited film.

WebNov 20, 2024 · Polymers can be amorphous or crystalline, depending upon a number of factors including the shape of their repeat unit, their molecular weight and their thermal history. Crystallinity in polymers is more complex than in other materials because of the long polymer chains. In some areas, the polymer chains align and pack together to form … WebBiodegradable poly (lactic acid) (PLA) usually has a crystallinity less than 10% due to its poor crystallization ability.
