Precursors for p-Type Nickel Oxide: Atmospheric-Pressure Metal-Organic Chemical-Vapour Deposition (MOCVD) of Nickel Oxide Thin Films with High Work Functions

A series of unsymmetrical nickel beta-diketonate derivatives have been synthesised and structurally characterised for application as atmospheric-pressure metal-organic chemical vapour deposition (AP-MOCVD) precursors for nickel oxide.TMEDA)Ni[MeC(O) CHC(O) OEt](2) (TMEDA = tetramethylethylenediamine) was selected and used to deposit NiO films of varying thickness onto commercial indium tin oxide (ITO)-coated glass; the work function of the ITO was raised as a consequence.
