This paper reports three types of nanorobotic end-effectors: m@CNTs-based sphere-on-pillar (SOP) optical nanoantennas, nanotube fountain pen, and m@CNTs-based tunneling nanosensor. The fabrication method of the m@CNTs-based SOP optical nanoantennas we developed has potentials in the investigation of nano-optics and nano-photonics due to its feasibility in preparing such devices. Nanotube fountain...
A novel rotary nanomotor is described using two axially aligned, opposing chirality nanotube shuttles. Based on intershell screw-like motion of nanotubes, rotary motion is generated by electrostatically pulling the two cores together. Simulations using molecular dynamics show the generation of rotation from armchair nanotube pairs and their actuation properties. The simulation results point toward...
Modes of melting and evaporation of metal at attogram level from individual carbon nanotubes (CNTs) are investigated experimentally using nanorobotic manipulation inside a transmission electron microscope. We compared the melting and evaporation induced by electric current, Joule heating, charge, and ionization. Experiments show that the most effective method is by positively ionizing the encapsulated...
This paper introduces the concept of nanoelectromechanical systems on a tip (NEMS-on-a-tip). As an example, force sensors based on the interlayer electromechanical coupling of individual multi-walled carbon nanotubes (MWNT) are designed with various configurations. The devices are fabricated and characterized using nanorobotic manipulation inside a scanning electron microscope (SEM). Experimental...
