文摘The Curie temperature and polarization in a ferroelectric cylinder with infinite length have been examined using Landau free energy expansion.The Curie temperature and polarization decrease with decreasing cylinder diameter for the positive extrapolation length,and reach zero at the critical size.For negative extrapolation length,both Curie temperature and polarization increase with decreasing cylinder diameter.
