Abstract

Abstract: In the era of molecular devices and nanotechnology, precise control over electron‐transfer processes is strongly desired. However, redox reactions are usually characterized by reaction equilibrium constants strongly departing from unity. This leads to strong favoring of either reactants or products and does not permit subtle control of transferred charge (doping). Here we propose, based on theoretical studies for periodic systems, how charge transfer between reactants could be finely manipulated in the epitaxially grown system composed of extremely strong oxidizer, reducing agent, and an inert separator—the key factor of control. Abstract : Redox reactions are quite difficult to control because their reaction equilibrium constants strongly depart from unity (particularly if at least one of the reactants is a potent oxidizing or reducing agent). Based on calculations, smooth control of charge transfer depending solely on the separation between oxidizer and reductant is proposed. AgF2, a powerful oxidizer, may be electron‐doped to a controlled extent using this approach.
