Compositional tuning of ternary solid solution semiconducting thin films can provide control over the physical properties of the films, and subsequently improve their technological performance. In this work, PbSxSe1-x solid solution thin films were chemically deposited on GaAs(100) substrates. Graded solid solutions as well as single-phase solid solutions with tunable compositions were obtained. Lattice parameters were extracted from X-ray diffraction and film compositions were calculated based on Vegard's law. It was concluded that PbSxSe1-x solid solution films can be chemically deposited in the entire range of compositions; however, each composition requires optimization of its own deposition conditions.
