Electrical devices are disclosed. The devices include an insulating substrate. A UO2+x crystal or oriented crystal UO2+x film is on a first portion of the substrate. The UO2+x crystal or film originates and hosts a non-equilibrium polaronic quantum phase-condensate. A first lead on a second portion of the substrate is in electrical contact with the UO2+x crystal or film. A second lead on a third portion of the surface is in electrical contact with the UO2+x crystal or film. The leads are isolated from each other. A UO2+x excitation source is in operable communication with the UO2+x crystal or film. The source is configured to polarize a region of the crystal or film thereby activating the non-equilibrium quantum phase-condensate. One source state causes the UO2+x crystal or film to be conducting. Another source state causes the UO2+x crystal or film to be non-conductive.
