in thin films
Also contains definition of: subphase in thin films
The terms substrate and subphase refer to a condensed phase that physically supports a @F02366@ or layer. The term substrate should be used with care in the light of the existing double meaning of the term substrate in @F02366@ science and technology, on the one hand, and in biochemistry, on the other. The term subphase applies, mainly, to a liquid phase underlying an adsorption layer or a floating @S05894@.
