Atomic Force Microscope Study of Ferroelastic Domains
In the present study, the authors have employed, for the first time, atomic force microscope (AFM) for studying domains in ferroelastic materials. Studies of ferroelectric/ferroelastic domains is important for understanding the acousto-optic, opto-electronic properties and the aging behavior of the ferroelectric/ferroelastic devices. In this paper we report our results on ferroelastic lead vanadate, Pb8V2O13 crystals. Both stripe and needle shaped domains are observed. The typical width of the tip of the needle domains is ~ 100 Å. Sharp and round tips of needles have been detected very clearly with developed surface features.
