Abstract

In this paper, we discuss an extension of a field theoretical approach for the description of the double layer containing ions of finite size. In particular, the density profile and the differential capacitance are presented in the low-temperature regime, and excluded volume effects are discussed. Simple approximations are presented which allow for analytic expressions. Our results are compared to Monte Carlo simulation data.
