Foreword
Given the increasingly important role of spectroscopic ellipsometry (SE) as a
real-time, non-perturbing, monitoring, and characterization tool in numerous
technological and biomedical applications, the editors, authors, and Springer are
commendedforpublishingthe2ndeditionofthismonograph,whichisdedicatedto
significantapplicationsofSEtofunctionalorganicsurfacesandthinfilms.Retained
topics from the first edition cover the adsorption of biomolecules at liquid–solid
interfaces, smart polymer surfaces and thin films for sensor applications, charac-
terization of nanoparticles and nanostructured surfaces and thin films, thin-film
organic semiconductors for photovoltaics and light emitters, and recent develop-
ments of SE instrumentation and related techniques over an extended optical
bandwidth.
New topics that appear in the 2nd edition include SE studies of bonding of
biomolecules on self-assembled monolayers, structure and interactions of hydrated
polymer thin films, ellipsometry of solvent-induced swelling at soft polymer
interfaces, optical properties of anisotropic thin films of organic dye aggregates,
relationship between morphology and optical properties of conjugated polymers,
and polarons in conducting polymers.
This updated monograph is a welcome contribution to the expanding ellip-
sometry literature.
