Abstract

Using simple models, analytical estimates of quantum capacitance C_Q are obtained for an infinite sheet, a nanoribbon, and a chain of two-dimensional analogs of the A_NB_{8 – N} compounds with a hexagonal structure (graphene-like compounds). It is demonstrated that there is a nonmonotonic dependence of C_Q on the electrostatic potential.
