在Jandau-Ginsburg-Devonshire(LGD)理论的基础上,建立了铁电纳米线的理论模型,并通过与第一原理计算结果的对比,建立了一种获取外延长度的新方法.对于Pb(Zr0 5 Ti0.5)0,(PZT)纳米线,其外延长度为20 nm.计算结果表明,在PZT纳米线中存在O.8 nm的临界直径,同时揭示了纳米线的表面效应对其铁电性能的抑制作用.

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.
