Not longer than ten years ago, a “ferroelectric” material was an insulating ternary oxide, whose ferroelectric properties died off when thinned down to a few tens of nanometers. Since 2016, new families of ferroic 2D materials (ferroelastic, ferroelectric, (anti)ferromagnetic, and multiferroic) have been deployed. In this talk, I will outline my involvement in the development of a family of ultrathin functional materials--2D ferroelectrics within the IV-VI material family [1-2]. My focus will be on the conceptual issues brought about by these new materials. I will then discuss some concepts behind the creation of multiferroic 2D materials. I will finish by hinting at the directions this new field appears to be heading to.
