Weyl semimetal is a three-dimensional material with a conical spectrum near an even number of point nodes, where two bands touch each other. Here we study spectral properties of surface electron states in such a system. We show that the density of surface states possesses a logarithmic singularity for the energy ε → 0. It decreases linearly at the intermediate energy of surface electron states and approaches zero as √(1-ε) for ε → 1. This universal behavior is a hallmark of the topological order that offers a new wide range of applications.
