Outer tube-selectively boron-doped double-walled carbon nanotubes for thermoelectric applications

Carbon nanotubes, the tiny hollow tube of hexagonal carbon lattices has been touted as one of the most promising materials for building items with fascinating electrical, thermal and mechanical properties. Selective functionality is realized by adding elements to the carbon nanotubes to make transistors, composite additives, field emitters and transparent conductive films. Carbon nanotubes doped with boron make the structure of the tubes more functional while increasing the ability to modulate the electrical properties. Boron-doping into coaxially aligned two single-walled carbon nanotubes (double-walled carbon nanotubes: DWNTs) show promise for use in electronic devices, composite materials, energy storage and power generation materials.
