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

Abstract

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_xTe_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.
