Caption

. "Sliding and Climbing a Ladder-Ferroelectric": The periodic crystal is made of two different atoms, repeating with constant separations in each horizontal layer. Sliding the layers to the right or left positions, to position the red atom above the blue (or vice versa), makes electrons jump up (or down) between the layers. Unlike common polar crystals, the interfacial ferroelectric system exhibits distinct, evenly spaced electric potential steps which can serve as individual information units.
