Prediction of the ferroelectric ground state of graphene and other
two-dimensional crystals [PDF]
S. A. MikhailovA spontaneous electric polarization in the many-body ground state of graphene and other similar materials, such as boron nitride and bilayer graphene, is predicted. This transition to the ferroelectric ground state is a consequence of strong Coulomb interaction between $\pi$-electrons in two-dimensional lattices.View original: http://arxiv.org/abs/1303.3928
