Abstract
Aerosol-assisted chemical vapour deposition (AACVD) of Cd[(SPiPr2)(SePiPr2)N]2 yields hexagonal
cadmium selenide and monoclinic cadmium phosphide films on glass substrates between 475 and 525 °C
at different argon flow rates. The films were characterized by X-ray powder diffraction (XRD), scanning
electron microscopy (SEM), energy dispersive analysis of X-rays (EDAX) and X-ray photoelectron spectroscopy (XPS). All the results of XRD, EDAX and XPS are in agreement with our previous investigations on Cd[(SePiPr2)2N]2. A breakdown mechanism is proposed based on mass spectra and density functional
theory calculations. A large peak at m/z 207 in the mass spectra, previously assigned by us as a new aromatic
species, is also observed for this complex.
