Junctions between metal and carbon nanotube (CNT) have been investigated mainly with transport experiments for the last several years. However, their detailed electronic and geometric structures are not fully revealed. We have created junctions between CNT and Ti metals by depositing the metal on CNT and the electronic and geometric structures have been studied with low temperature scanning tunneling microscopy. Ti metal is preferentially coated near the edges and in the gaps between CNTs. In spatially resolved tunneling spectroscopy, the metallic states are observed on Ti surfaces and the state extended into CNT area, suggesting the existence of mixed states near the junctions@footnote 1@. The origin of the mixed states and observed screening lengths will be discussed. @FootnoteText@ 1) S. Dag, E. Durgun, and S. Ciraci, Phys. Rev. B 69, 121407(R) (2004).
