During the last years, a lot of efforts have been devoted to the understanding of finite size effects in ferroelectric nanostructures, both experimentally and theoretically [1]. Most of these studies concerned ferroelectric thin films and multilayers. Here, I will discuss some recent results concerning the first-principles modeling of ferroelectric perovskite ultrathin layers in various environments: in contact with a metal [2-6], an incipient ferroelectric [7], a regular dielectric [8] or a magneto-electric compound.
