In article number 1700449 , Jan M. Van Ruitenbeek and co‐workers study the time evolution of the conduction of SrTiO 3 near the glass‐transition temperature of an ionic liquid. The top surface of the crystalline SrTiO 3 insulator can be converted into a good conductor by application of a gate potential, mediated by the ionic liquid. The process by which the conducting layer forms can be followed by cooling the ionic liquid to a temperature close to the glass transition, here about 185 K.
