abstract = {he influence of the supporting surface on the standing wave electronic modes of finite metallic carbon nanotubes (CNTs) is discussed. The charge distribution of the states is visualized by simulating the energy resolved scanning tunneling spectroscopy (STS) maps. The Fourier transform of the spatial patterns exhibited by the STS maps allows to reconstruct the dispersion relation, whose definiteness is smeared out for increasing surface-tube interaction strengths. The scattering of the modes in the tube due to the interaction with the surface causes distortions of the simulated maps. For example, the reflection symmetry with respect to the mirror plane perpendicular to the tube axis appears to be broken for modes in the case of narrow tubes, when the interaction with the surface is strong enough.}}
