Transistor behavior via Au clusters etched from electrodes in an acidic gating solution: Metal nanoparticles mimicking conducting polymers

摘要: We report that the electrical conductance between closely spaced gold electrodes in acid solution can be turned from off [insulating; I] to on [conducting; C] again by monotonically sweeping a gate voltage applied solution. propose this ICI transistor action is due an electrochemical process dependent nanoparticles etched surface of electrodes. These measurements mimic characteristics nanoscale acid-gated polyaniline transistors, so researchers should guard against misinterpreting effect future molecular-electronics experiments.
