Precursors for PbTe, PbSe, SnTe, and SnSe synthesized using diphenyl dichalcogenides

We create precursors for PbTe, PbSe, SnTe, and SnSe by reacting Pb or Sn with diphenyl dichalcogenides in a variety of different solvents. We then deposit PbSe x Te 1− x thin films using these precursors and measure their thermoelectric properties. Introducing Na-dopants into the films allows the th...

Description
Summary:We create precursors for PbTe, PbSe, SnTe, and SnSe by reacting Pb or Sn with diphenyl dichalcogenides in a variety of different solvents. We then deposit PbSe x Te 1− x thin films using these precursors and measure their thermoelectric properties. Introducing Na-dopants into the films allows the thermoelectric properties to be varied. Alternative metal chalcogenide precursor syntheses (instead of hydrazine or thiol-amine approaches) along with corresponding thermoelectric properties of PbSe x Te 1− x films.
