Optical Characterization of Band Diagram Properties of Germanium-Chalcogenide and Silver Doped Thin-Films

Mentor: Michael Kozicki, Yago Gonzalez Velo
FURI: Fall 2018

The band diagram properties of germanium-chalcogenide thin films doped with silver are of interest due to their ability to become ionic conductors. Optically characterizing these thin films using UV-Visible Spectroscopy and Ellipsometry gives insight to the band diagram properties. In particular, the optical band-gap, refractive index, and absorption coefficient are the parameters that are discovered from the analysis techniques. It has been found that the optical band-gap decreases with increasing silver content. Understanding the physical properties of these thin films is the key to implementation in useful devices.
