The formation of misfit dislocations in epitaxial growth of 2.1% lattice-mismatched EuTe on PbTe (111) was studied using ultrahigh vacuum scanning tunneling microscopy. It is shown that at the critical layer thickness straight monolayer surface step lines appear as a result of glide of threading dis
