  • Abstract
    The variation by a factor of 2 in the observed permittivity of yttrium oxide film is explained in terms of interfacial polarization based on the Y2O3/SiO2 double-layer model. Provided the dielectric relaxation time constants of the two layers are grossly dissimilar, the model can also explain the frequency independence of the composite capacitor.
