ABSTRACT
We have measured the local current density on individual single-wall carbon nanotubes (SWNTs) with the conducting tip of an atomic force microscope; the SWNTs make up a nanometer-scale electronic circuit on an insulating substrate. Scanning tunneling spectroscopy measurements at certain positions on a SWNT bundle show that both metallic and semiconducting nanotubes can coexist in a bundle. The approach applied in this experiment appears as a powerful technique for the investigation of the spatial variation of current density and electronic states of nanometer-scale electronic devices.

    Atomic force and lateral force microscopes use a four quadrant p-i-n detector to measure the motion of a laser beam reflected from the top of a cantilever. If the detector is rotated slightly in the plane of the p-i-n diode, this will cause frictional forces to be detected as a false height...

    We use a conducting-tip atomic force microscope (CT-AFM) to measure the local electronic properties of single wall carbon nanotube (SWNT) circuits. Tunnel current images of SWNTs in circuits can have 1 nm resolution, much better than that of standard AFM. By using the tip as a mobile electrode,...

    An atomic force microscope (AFM) has been used to modify the electrical properties of carbon nanotube devices. By applying voltage pulses from a metal-coated AFM tip, electrical breaks ("cuts") or tunneling barriers ("nicks") can be created at any point along a tube. These methods are applied to...
