Preferred Label : characteristic length;
Detailed label : characteristic length in thin films;
IUPAC definition : The term characteristic length or scale refers, in general, to the parameter which
characterizes the density profile (of a given physical quantity). The static (equilibrium)
or dynamic character of a characteristic length must be specified. The terms out of
plane and in plane refer to characteristic lengths normal or parallel to the interface,
respectively. Since interfacial layer 'thickness' and characteristic length correspond
to various concepts, the current usage where an out of plane characteristic length
is referred to as the interfacial layer thickness, is confusing and should be abandoned.;
