Photoemission Spectroscopy Characterization of Attempts to Deposit MoO2 Thin Film

الملخص EN

Attempts to deposit molybdenum dioxide (MoO2) thin films have been described.

Electronic structure of films, deposited by thermal evaporation of MoO2 powder, had been investigated with ultraviolet photoemission and X-ray photoemission spectroscopy (UPS and XPS).

The thermally evaporated films were found to be similar to the thermally evaporated MoO3 films at the early deposition stage.

XPS analysis of MoO2 powder reveals presence of +5 and +6 oxidation states in Mo 3d core level along with +4 state.

The residue of MoO2 powder indicates substantial reduction in higher oxidation states while keeping +4 oxidation state almost intact.

Interface formation between chloroaluminum phthalocyanine (AlPc-Cl) and the thermally evaporated film was also investigated.
