Charge carrier transition in an ambipolar single-molecule junction: Its mechanical-modulation and reversibility

Single-molecule switch for modular electronics Applying force to a junction linking gold atoms leads to reversible switching of its electric properties, facilitating development of single-molecule devices. Building electronics from the molecular level up could lead to drastically smaller electronic...
