Fullerene nanotubes as transporting and focusing elements of nanoscale beam technology

The nanotubes with a diameter of 1–100 nm and length of 1 mm are shown to be effective tools in future developments related to microelectronics and nanonscale beam technology. Straight and bended nanotubes allow the transporting and deflecting of neutral and charged particle beams with great efficiency. Combined with the cantilever of the atomic-force microscope, nanotubes make it possible to carry out the surface modification omitting standard technological stages accepted in microelectronics. Also, it is possible to get hard electromagnetic radiation by relativistic electrons and positrons, accepted in bound states of the transverse energy spectrum. The radiation cooling of the nanotubes heated by particle beams proved to stabilize their temperature at approximately 200–300 K.
