Abstract
Ferroelectrics have received intense attention due to its great application potential in RAM devices and new types of sensors. The stability issue of ferroelectric domain in lead meta niobate (PbNb2O6) single crystal for its manipulation using electric field at nano scale control on the geometrical dimensions of domain is reported, which is highly desirable for both applications and fundamental study. The analytical parameters like critical radius of nucleation of domain (rc), domain wall energy (α), critical energy of nucleation (ωc), geometrical dimensions of domain for this peculiar ferroelectric crystal are calculated and condition of back-switching on removal of applied electric field is discussed.
