About this document
Nanoscale Ferroelectric Geometries Analysis by Jeff Webb is a document available to read on EtoBox.
This chapter introduces Landau-Devonshire theory for calculating spontaneous polarization profiles in ferroelectric materials of different geometries, including films, strips, and boxes, at the nanoscale. Landau-Devonshire theory models the free energy of ferroelectrics as a function of polarization and is used to determine the polarization configuration that minimizes the free energy. The chapter provides background on Landau-Devonshire theory and ferroelectric phase transitions, then applies the theory to
