Abstract

We report electrostatic and piezoelectric properties of the atomic-level-controlled clean surface of BaTiO₃ single crystals in ultra high vacuum (UHV), which has not been reported so far. The results are analyzed by the surface conduction measurements in UHV, reexamination of 180 domain theory, ab-initio calculations.
