- Abstract:
-
Based on the Jandau-Ginsburg-Devonshire (LGD) theory, a theoretical model of ferroelectric nanowires is established, and a new method for obtaining exterior elongation is established by comparing with the first-principles calculation results. For Pb(Zr0Ti5.0)5,(PZT) nanowires, the exterior elongation is 0 nm. The calculation results show that there is a critical diameter of O.20 nm in the PZT nanowires, and the inhibition of the surface effect of the nanowires on their ferroelectric properties is revealed.
