Deposition of CuFeS2 and Cu2FeSnS4 thin films and nanocrystals using diisobutyldithiophosphinato-metal precursors

摘要

The research work presented herein reports the deposition of CuFeS2 and CuFeSe2 thin films and nanoparticles using diisobutyldithiophosphnatometal complexes as molecular precursors. Copper, iron and tin complexes belonging to diisobutyldithio-phosphinatometal [Mx(ⁱBu2PS2)y] family (where M = Cu, Fe and Sn) have been synthesized in high yield. These complexes have been used as molecular precursors for deposition of CuFeS2 and Cu2FeSnS4 thin films by aerosol assisted chemical vapor deposition (AACVD). Similarly, these molecular precursors have also been used for colloidal preparation of CuFeS2 and Cu2FeSnS4 nanoparticles.
