Abstract
We report voltage-driven electrical bistability in an organic semiconductor, namely Ponceau SS. Conductance switching to different levels or "multilevel switching" in devices based on thin-films is due to different density of high-conducting molecules. In a monolayer of Ponceau SS, we have observed one low-conducting and two high-conducting states. This is due to three configurable planes of the molecule exhibiting at least two stable high-conducting conformers. Apart from establishing conductance switching to be a molecular phenomenon, the multilevel conductance in a monolayer shows that a single molecule can exhibit multilevel memory application.
