Inside Back Cover: Light-Driven Bipolar Electrochemical Logic Gates with Electrical or Optical Outputs (ChemElectroChem 3/2016).

AND and OR logic gates are made with silicon and carbon materials and operated by using bipolar electrochemistry. Such devices require electrical and light inputs to function and generate an electrical output or, alternatively, an optical output that can be readily observed with the naked eye.
