| contents | The remarkable advances achieved in two-dimensional materials are now being directly transposed to low-dimensional oxides. Here we show using first-principles-based atomistic simulations that ultrathin freestanding ferroelectric layers host a rich variety of polar states, from liquid-like ferroelectric domains with long-range orientational order to helix-wave and chiral bubbles configurations reminiscent of those observed in twisted freestanding oxide layers. Time-dependent electric fields enable reversible control, revealing freestanding oxide layers as ideal platforms to explore complex polar states and their potential applications in future ferroic devices. |
