Reversible Switching Phenomenon in Diarylethene Molecular Devices with Reduced Graphene Oxide Electrodes on Flexible Substrates

such as rectifi ers, transistors, memories, and photoswitches. [ 1–18 ] However, molecular devices suffer from a very low device yield because it is diffi cult to attach metal electrodes on a molecular size scale. For example, in a vertical metal–molecule– metal junction structure, the metal deposited in the top electrode penetrates into the existing molecular monolayer to the bottom electrode, thus causing problems with electrical short circuits and a typical device yield of less than ≈1%. [ 19–21 ] To resolve the low-yield problems, intermediate layers of conducting polymer [ 22–25 ]
