英文摘要：
An analytical method to compute the LDOS energy spectrum and stationary states for finite size doped monatomic chains modelled by an effective one-dimensional tight-binding hamiltonian is presented. It is based on the formal solution of linear second order recurrence relations. We also study the LDOS energy spectrum of some doped monatomic chains applying a perturbative approach to the characteristic equation of the reference metallic structure doped with a few extraneous atoms.
