Synthesis and Characterization of Thin Films

In this study, we investigated the properties of gold thin films. We synthesized samples thinner than 50 nm by sputtering gold onto glass substrates. We subsequently characterized the electrical properties of the thin films between room temperature and 10 K. The optical properties were determined through spectroscopy measurements between 300 to 1,000 nm by recording transmission and reflection data and extracting the absorption coefficient of our samples. We consider a method of using the absorption coefficient to determine the thickness of thin films.
