“…Post-deposition annealing in nitrogen has been shown to produce more conductive and less transparent films due to increased oxygen vacancy (V o ) defects [128]. On the other hand, less conductive and more transparent films are produced by annealing ITO in an oxygen ambient [128]. In our own experiments, we have observed significant changes in the dielectric function of e-beam evaporated ITO films annealed in different ambient environments, as shown in Fig.…”

Plasmonics is a research area merging the fields of optics and nanoelectronics by confining light with relatively large free-space wavelength to the nanometer scale -thereby enabling a family of novel devices. Current plasmonic devices at telecommunication and optical frequencies face significant challenges due to losses encountered in the constituent plasmonic materials. These large losses seriously limit the practicality of these metals for many novel applications. This paper provides an overview of alternative plasmonic materials along with motivation for each material choice and important aspects of fabrication. A comparative study of various materials including metals, metal alloys and heavily doped semiconductors is presented. The performance of each material is evaluated based on quality factors defined for each class of plasmonic devices. Most importantly, this paper outlines an approach for realizing optimal plasmonic material properties for specific frequencies and applications, thereby providing a reference for those searching for better plasmonic materials.

“…refractive index, dielectric constant and absorption coefficient, over a wide wavelength (k) range and optical band gap values of thin films, is crucial for optimizing their optical and electrical properties especially for solar cell applications. Therefore, determination of the optical constants of e-beam evaporated absorbing AIS thin films, both as-deposited and annealed samples at different ambient temperatures, was performed by transmission measurement, since the optical transmission measurement at a specific wavelength spectrum is a simple and effective experimental method for this purpose [12][13][14][15].

“…Tin-doped indium oxide (In 2 O 3 :Sn) or ITO, as a typical transparent conducting oxide (TCO), has received extensive studies for its use in applications such as flat panel displays and solar cells [1][2][3]. In preparing TCOs, In 2 O 3 is always treated as a substrate material, while Sn is considered an adjusting element to obtain low resistivity (b200 μΩ cm) and high transmittance (N90%) in the visible light range of the spectrum [4,5].…”
