Influence of Bias on the Friction Imaging of Ferroelectric Domains in Single Crystal Barium Titanate Energy Storage Materials

Figure 1

The morphologic image (a) and the friction images on a same region of the newly cleaved surface of single crystal multidomain BaTiO₃ under three different experimental conditions: without voltage bias (b), +12 voltage (c), and −12 voltage (d). The specimen stage is grounded.
