摘要
In this communication we obtain an approximate formula for the effective electrical conductivity for a two-component two-dimensional material. The basis of the formula is Keller's reciprocity theorem. The derived formula satisfies the reciprocity condition at-all values of the concentration, and the predictions of the formula agree well with data on the electrical conductivity of several two-component materials.
