Based on a well-known tight-binding Hamiltonian formulation of carbon nanotubes, the local density of states of semiconductor-metal double-wall carbon nanotubes (DWCNTs) is evaluated numerically. The results verify that the semiconductor shells in contact with the nearby metallic shells become metallic, a direct evidence of a metallic proximity effect. This proximity effect can be used to explain the anomalous field effect characteristics observed in the field effect transistors made of the semiconductor-metal-type DWCNTs.
