The semiconductivity and stability of palladium oxide Academic Article uri icon

abstract

  • Films of palladium oxide of good optical quality have been prepared by the oxidation of sputtered films of palladium. Optical absorption and photoconductivity measurements indicate extrapolated band gaps of 2.13±0.03 eV and 2.67±0.03 eV respectively with the photoconductivity showing an exponential tail extending to lower energies. Measurements of the thermal stability of the films in the presence of a low partial pressure of oxygen indicate a dissociation enthalpy of -1.17±0.06 eV. The presence of hydrogen in the ambient during decomposition was found to reduce the temperature for decomposition to palladium metal from about 580 to 350 K. © 1978 Chapman and Hall Ltd.
