Thin Film Materials (I)
Thin Film Materials (I). Thin films are used extensively in sensor applications. The typical thin-film deposition is less than 10 m thick. Many films are less than 1 m thick thus implying nanoscale dimensions. There are several methods of applying thin-films. Physical vapor deposition
