Structural and optical properties of AgIn5S8 films grown by pulsed laser deposition
- 27 Downloads
Thin AgIn5S8 films are grown on glass substrates by pulsed laser deposition using bulk crystals as targets, and their structure, chemical composition, surface morphology, and optical properties (transmission and reflection spectra in the range 0.5–2.5 µm) are investigated. The transmission and reflection data are used to evaluate the absorption coefficient of the films and the energies of direct and indirect interband transitions. The results obtained for laser-deposited AgIn5S8 films agree well with those for bulk crystals.
