- Present work reports the correlation between structural, ferroelectric
and transport properties of Zn1 xMgxO nanoparticles synthesized
by sol–gel method, and their local electronic structures.
Attributes of structural distortion are observed in Mg doped
samples, which was confirmed by Rietveld refinement of X-ray diffraction
pattern. Distortion in bond length of the samples occurs
with the Mg substitution on the Zn site. The change in bond length
(Zn–O) enhances the polarization and hence, an improvement in
ferroelectric nature is realized after Mg doping. Moreover, the Mg
incorporation increases the electrical resistivity of the samples.
These properties are correlated with the local electronic structures
provided by X-ray absorption spectroscopy.
