Molecule-independent electrical switching in Pt/organic monolayer/Ti devices

Electronic devices comprising a Langmuir-Blodgett molecular monolayer sandwiched between planar platinum and titanium metal electrodes functioned as switches and tunable resistors over a 10(2)-10(5) Omega range under current or voltage control. Reversible hysteretic switching and resistance tuning was qualitatively similar for three very different molecular species, indicating a generic switching mechanism dominated by electrode properties or electrode/molecule interfaces, rather than molecule-specific behavior.
