Abstract We present a theoretical study of the influence of d orbitals on the evolution of the current tunnelling between the transition metal STM tip and the transition metal surface. This problem is considered for the system formed by Ni(001) surface and Pt tip. We have found that the tunnelling between d orbitals of the transition metal surface and of the apex atom of the transition metal tip may produce very sharp image of the metal surface, contrary to the tunnelling through weakly localized sp orbitals. The high effectivity of the tunnelling through this d–d channel is limited to very small tip-substrate separation.
