The collective dipole behaviors in (BaTiO3)m/(SrTiO3)n composite nanowires are
investigated based on the first-principles-derived simulations. It demonstrates
that such nanowire systems exhibit intriguing dipole orders, due to the combining
effect of the anisotropic electrostatic interaction of the nanowire, the
SrTiO3-layer-modified electrostatic interaction and the multiphase ground state
of BaTiO3 layer. Particularly, a strong polar-toroidal coupling that is tunable
by the SrTiO3-layer thickness, temperature, external strains and electric fields
is found to exist in the nanowires, with the appearance of fruitful dipole states
(including those being purely polar, purely toroidal, both polar and toroidal, or
distorted toroidal) and phase boundaries. As a consequence, an efficient cross
control of the toroidal (polar) order by static (curled) electric field, and
superior piezoelectric and piezotoroidal responses, can be achieved in the
nanowires. The result provides new insights into the collective dipole behaviors
in nanowire systems.
