Control over the Tc value of high-Tc superconductors by self-assembled monolayers is demonstrated (Tc=critical temperature). Molecular control was achieved by adsorption of polar molecules on the superconductor surface (see scheme) that change its carrier concentration through charge transport or light-induced polarization.
