Hiromichi Kataura
Encyclopedia
is a Japanese scientist known for his work on synthesis and characterization of single-wall and double-wall carbon nanotube
s and on encapsulation of water, fullerene
and other organic molecules into carbon nanotubes.
Kataura is the leader of self-assembled nano-electronics group at the National Institute of Advanced Industrial Science and Technology
(AIST).
Kataura plot is a graph relating the energy of the band gap
s in a carbon nanotube and its diameter. A nanotube of certain diameter can be metallic M or semiconducting S; it can have several band gaps, conventionally labeled as S11, S22, M11, M22, etc. This property results in multiple branches in the Kataura plot.
The original article on the Kataura plot has been reported in a lesser-known journal Synthetic Metals. Nevertheless, this article has been cited more than 900 times in refereed journals published between 2000 and March 2010.
Carbon nanotube
Carbon nanotubes are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, significantly larger than for any other material...

Fullerene
A fullerene is any molecule composed entirely of carbon, in the form of a hollow sphere, ellipsoid, or tube. Spherical fullerenes are also called buckyballs, and they resemble the balls used in association football. Cylindrical ones are called carbon nanotubes or buckytubes...

Band gap
In solid state physics, a band gap, also called an energy gap or bandgap, is an energy range in a solid where no electron states can exist. In graphs of the electronic band structure of solids, the band gap generally refers to the energy difference between the top of the valence band and the...
