Polarization configuration in ferroelectric nanosprings.
(a) Helix polarization structure in ferroelectric nanosprings in the absence of external fields. The line element and cross-section of the ferroelectric nanospring show a detailed polarization distribution in a local area. (b) Right-handed (RH) polar superhelix in the ferroelectric nanospring under tensile load of W = 240 μN. (c) Left-handed (LH) polar superhelix in the ferroelectric nanospring under the compressive load. The contour colour indicates the direction of the polarization vectors in the cross-section of the nanospring.
