Four-Way Switch Promises Greater Tunability of Layered Materials

Caption

Van-der-Waals layered CuInP2S6 has different properties depending on the locations of copper atoms (orange spheres). Unified theory and experiment led to the discovery of two co-existing phases which are connected through a quadruple energy well whose properties can be harnessed to provide materials with new functions.
