Modifying chirality with electricity: Voltage-driven method enables reversible, tunable states

Researchers at Science Tokyo have demonstrated a way to electrically change the chirality of organic-inorganic hybrid materials, in which chiral molecules adsorb onto inorganic surfaces. Using an electric double-layer transistor with a chiral electrolyte, specific chirality was imposed on an otherwise achiral molybdenum disulfide surface. This reversible method enables tunable chiral electronic states and opens new possibilities for advanced spintronic devices and the emerging field of “chiral iontronics”.
