Experiments have shown that insulating behavior emerges in graphene bilayers when the moire bands are partially filled and the top layer is rotated relative to the bottom layer. By calculating charge distributions and estimating excitation gaps, researchers are able to further understand the properties of these phases.
Experiments on graphene bilayers, where the top layer is rotated with respect to the one below, have displayed insulating behavior when the moire bands are partially filled. We calculate the charge distributions in these phases, and estimate the excitation gaps.
