Electronic processes in scanning tunneling microscopy of carbon nanotubes

Description

An LCAO theory of the tunneling current between carbon materials (sp2) and a metallic tip is developed to simulate their differential conductance and STM images. The tunneling current is expressed by a series expansion of the resolvent operator which is computed with a recursion algorithm. The differential conductance of both chiral and achiral nanotubes is calculated. We emphasize the fact that electronic and geometrical effects must be interpreted with much attention in STM imaging of carbon nanotubes
