We consider a two-dimensional random band matrix ensemble, in the limit of infinite volume and fixed but large band width W. For this model, we rigorously prove smoothness of the averaged density of states. We also prove that the resulting expression coincides with Wigner’s semicircle law with a precision $$W^{-2+\delta },$$W-2+δ, where $$\delta \rightarrow 0$$δ→0 when $$W\rightarrow \infty .$$W→∞. The proof uses the supersymmetric approach and extends results by Disertori et al. (Commun Math Phys 232(1):83–124, 2002) from three to two dimensions.
