"Sliding and climbing between electrical polarizations": The periodic crystal structure contains a pair of atoms at regular intervals in each horizontal layer. Each additional layer can be slid to the right or left in the horizontal plane to place a blue atom exactly above a red atom or vice versa, thereby bouncing electrons with an electrical charge up or down between the layers. Unlike in polarized crystals known so far, the electric potential in the new system changes in a constant and well-defined value between each step. It is possible to climb in a controlled manner between all the different options, that is, it is possible to switch between the information units in the same crystal in contrast to a pair of modes in previous technologies.
