Light-Driven Bipolar Electrochemical Logic Gates with Electrical or Optical Outputs
Abstract
We present the design of AND and OR logic gates made with silicon and carbon materials and operated by bipolar electrochem. Such devices require elec. and light inputs to function and generate an elec. output or, alternatively, an optical output that can be readily obsd. with the naked eye. These operators are stable over time and can work in a wide range of electrolyte concns. Finally, we show that the input elec. potential can be considerably lowered in the presence of the FeIII(CN)63-/FeII(CN)64- redox couple in soln.
