Where carrier densities are similar (ITO and nanoparticle Au), the plasmonic behavior is that of a monolithic ITO thin film. Where the carrier density of one layer is much greater than that of the other (ITO and Au metal), boundary conditions lead to cancelation of the surface plasmon. In the latter case a capacitivelike plasmon resonance is observed for sufficiently thin films.}, number={18}, journal={OPTICS LETTERS}, author={Franzen, Stefan and Rhodes, Crissy and Cerruti, Marta and Gerber, Ralph W. and Losego, Mark and Maria, Jon-Paul and Aspnes, D.

Optical studies with coupling in the Kretschmann configuration reveal an angle-dependent plasma frequency in the mid-IR for p-polarized radiation, suggestive of the detection of a Drude plasma frequency. These studies are complemented by oxygen depletion density functional theory studies for the calculation of the charge carrier concentration and plasma frequency for bulk AZO. In addition, we report on the optical and physical properties of thin film adlayers of n-hexadecanethiol (HDT) and n-octadecanethiol (ODT) self-assembled monolayers (SAMs) on AZO surfaces using reflectance FTIR spectroscopy, X-ray photoelectron spectroscopy (XPS), contact angle, and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy. Our characterization of the SAM deposition onto the AZO thin film reveals a range of possible applications for this conducting metal oxide.}, number={2}, journal={LANGMUIR}, author={Rhodes, Crissy L. and Lappi, Simon and Fischer, Daniel and Sambasivan, Sharadha and Genzer, Jan and Franzen, Stefan}, year={2008}, month={Jan}, pages={433–440} } @article{rhodes_cerruti_efremenko_losego_aspnes_maria_franzen_2008, title={Dependence of plasmon polaritons on the thickness of indium tin oxide thin films}, volume={103}, number={9}, journal={Journal of Applied Physics}, author={Rhodes, C. and Cerruti, M. and Efremenko, A. and Losego, M. and Aspnes, D.

The reflectance of the CTO films was dependent upon the incident angle of the impinging radiation and revealed a reflectance decrease indicative of a plasma frequency in the mid-IR using p-polarized radiation.}, number={8}, journal={THIN SOLID FILMS}, author={Rhodes, Cnissy L. and Brewer, Scott H. and Folmer, Jaap and Franzen, Stefan}, year={2008}, month={Feb}, pages={1838–1842} } @article{cerruti_rhodes_losego_efremenko_maria_fischer_franzen_genzer_2007, title={Influence of indium-tin oxide surface structure on the ordering and coverage of carboxylic acid and thiol monolayers}, volume={40}, ISSN={["1361-6463"]}, DOI={10.1088/0022-3727/40/14/016}, abstractNote={This paper analyses the variability of self-assembled monolayers (SAMs) formation on ITO depending on the substrate surface features. In particular, we report on the formation of carboxylic acid- and thiol-based SAMs on two lots of commercially prepared indium–tin oxide (ITO) thin films. Contact angle measurements, electrochemical experiments, and near-edge x-ray absorption fine structure (NEXAFS) spectroscopy showed that the quality of monolayers formed differed substantially between the two ITO batches. Only one of the two ITO substrates was capable of forming well-organized thiol- and carboxylic acid-based SAMs. In order to rationalize these observations, atomic force microscopy and x-ray diffraction analyses were carried out, and SAMs were prepared on ITO substrates fabricated by sputtering in our laboratories. An attempt was made to influence the film microstructure and surface morphology by varying substrate temperatures during ITO deposition. Good-quality thiol and carboxylic acid SAMs were obtained on one of the ITO substrates prepared in-house. While our characterization could not single out conclusively one specific parameter in ITO surface structure that could be responsible for good SAMs formation, we could point out homogeneous surface morphology as a relevant factor for the quality of the SAMs. Evidence was also found for ITO crystallographic orientation to be a parameter influencing SAMs organization.}, number={14}, journal={JOURNAL OF PHYSICS D-APPLIED PHYSICS}, author={Cerruti, Marta and Rhodes, Crissy and Losego, Mark and Efremenko, Alina and Maria, Jon-Paul and Fischer, Daniel and Franzen, Stefan and Genzer, Jan}, year={2007}, month={Jul}, pages={4212–4221} }
