Polar properties and local piezoelectric response of ferroelectric nanotubes
We consider the polar properties of the ferroelectric nanotubes within the
 framework of Landau-Ginzburg-Devonshire phenomenology. The approximate
 analytical expression for the paraelectric-ferroelectric transition temperature dependence
 on the radii of nanotube, polarizati...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | We consider the polar properties of the ferroelectric nanotubes within the
framework of Landau-Ginzburg-Devonshire phenomenology. The approximate
analytical expression for the paraelectric-ferroelectric transition temperature dependence
on the radii of nanotube, polarization gradient, extrapolation length, elastic stresses and
strains arising from surface tension and thermal expansion mismatch, and electrostriction
coefficient was derived. We calculated effective local piezoresponse of the ferroelectric
nanotube within decoupling approximation of electric and elastic problem. Obtained
results explain the ferroelectricity conservation in Pb(Zr,Ti)O₃ and BaTiO₃ nanotubes
observed by using Piezoelectric Force Microscopy
