Determination of critical points on silicon nanofilms: Surface and quantum confinement effects

Lioudakis, Emmanouil E.; Othonos, Andreas S.; Nassiopoulou, Androula Galiouna (2008)

In this work, we present a comprehensive study of the optical properties of nanocrystalline silicon films with thickness varied from 5 to 30 nm. Spectroscopic ellipsometry is employed to determine the dielectric functions ...

Direct observation of excitons in polymer/carbon nanotube composites at room temperature: The influence of nanotube concentration

Lioudakis, Emmanouil E.; Kanari, C.; Othonos, Andreas S.; Alexandrou, Ioannis (2008)

In this work, we have employed spectroscopic ellipsometry technique to study the optical properties of polymer/carbon nanotube (CN) composites as a function of nanotube concentration. Using a two-layer structural model ...

Selected antenna applications of Negative-Refractive-Index Transmission-Line (NRI-TL) metamaterials

Eleftheriades, G. V.; Antoniades, Marcos A.; Qureshi, F. (2006)

Metamaterials (MM) that exhibit a simultaneously negative electric permittivity E and magnetic permeability μ, and thus a negative refractive index (NRI), have recently attracted considerable attention in the electromagnetics ...
