摘要：

The radial electromechanical properties of carbon nanotubes have been measured. The electrical conductance of single-walled carbon nanotubes (SWNTs) as a function of the loading force and bias voltage applied by an atomic force microscope tip is reported (see Figure). An increase of the conductance due to the tip-SWNT electrical contact formation and a drop of the conductance at high loading forces due to radial molecule deformation are observed (see also inside front cover).
