The self-interstitial in silicon is studied as function of its position in between the tetrahedral and the hexagonal sites with the large-unit-cell pseudopotential method. The energy level scheme of the impurity stems from the interaction between the atomic orbitals of the interstitial and nearest-neighbour host crystal bonding orbitals. The striking changes in electronic structure along the path are not due to a variation of the impurity potential but rather to that of the host crystal environment.
