We review the manifestations of electrostatic interactions, and in particular polarity effects, in oxide ultra-thin films and two-dimensional nano-objects. We discuss the efficiency of various compensation mechanisms such as overall structural transformations, strong lattice relaxations, inhomogeneous charge redistributions, support effects, and/or the formation of 2D or 1D electron/hole gases.
