The electronic structure of the <100>{010} edge dislocation was calculated by using the real-space tight-binding linear muffin-tin orbital recursion method, including a self-consistent treatment of electron density redistribution effects in the core. It was demonstrated that quasi-localized states could exist in this system as a result of specific lattice distortions in a dislocation core with so-called broken bonds.
