Research reveals the thinnest possible ladder steps made of distinct electric potentials

Tel Aviv University research reveals two-dimensional crystals exhibiting a unique control of distinct electric potential steps by sliding atomically thin layers against each other. The consecutive, ultimately thin, electrical switches reported are a highly desired resource for information technology and novel electro- and optomechanical applications.

The research, now published in Nature, was conducted by Dr. Swarup Deb, M.Sc. student Noam Raab, Prof. Moshe Goldstein, and Dr. Moshe Ben Shalom, all from the Raymond & Beverly Sackler School of Physics & Astronomy at Tel Aviv University, and Dr. Wei Cao, Prof. Michael Urbakh and Prof. Oded Hod from the Chemistry School at TAU, and Prof. Leeor Kronik from the Weizmann Inst.

Dr. Moshe Ben Shalom, head of the Quantum Layered Matter Group, says, “We are fascinated by how the atoms in a condensed matter order, how electrons choose to mix between the atoms and if or how external stimulus can manipulate the atomic order and the electric charge distribution.”
