Direct Measurement Of Chiral Structure And Transport In Single- And Multi-Walled Carbon Nanotubes
JOURNAL OF PHYSICS-CONDENSED MATTER(2016)
摘要
Electrical devices based on suspended multi-wall carbon nanotubes were constructed and studied. The chiral structure of each shell in a particular nanotube was determined using nanobeam electron diffraction in a transmission electron microscope. The transport properties of the carbon nanotube were also measured. The nanotube device length was short enough that the transport was nearly ballistic, and multiple subbands contributed to the conductance. Thermal excitation of carriers significantly affected nanotube resistance at room temperature.
