| 中文摘要 | A model for ferroelectric nanowire calculation was established based on the Landau - Ginsburg - Devonshire(LGD) theory and a new method to obtain the extrapolation length was developed. It is revealed that the extrapolation length of Pb(Zr/sub 0.5/Ti/sub 0.5/) O/sub 3/ (PZT) nanowire is 20 nm and its critical diameter is 0.8 nm. Our results further show that the surface effect suppresses the ferroelectricity in the PZT nanowire. |
