• We investigate a freezing transition of strongly correlated electrons in coupled twodimensional layers in the presence of small levels of disorder. When the layers are far apart the ground state of the system is the liquid phase. We find at a critical layer spacing that a transition occurs to a coupled glassy phase. The driving mechanism for this is the interaction between electrons in the two layers. This acts on a given electron like an external disorder potential which enhances the effect of the disorder already existing in the layer backgrounds. The nonergodicity parameters for the electrons are calculated within a mode coupling formalism. Strong electron-electron correlations are essential for the transition to occur.
