Copper-based ternary chalcogenides thin films fabricated by PLD as potential thermoelectrics

摘要

Two promising thermoelectrics, copper-based chalcogenides, have been fabricated as thin films by Pulsed Laser Deposition. For the fabrication a single target (Cu3SbSe4) has been used for both materials, the deposition conditions dictating whether Cu3SbSe3 or Cu3SbSe4 is formed. The thin film structures thus obtained have been investigated by XRD and SEM/EDX. (C) 2019 Elsevier B.V. All rights reserved.
