4 wire measurement of metallic carbon nanotubes.

You said that the electrical contacts are a significant perturbation on the resistivity of carbon nanotubes. Well, I can imagine that over a very short range that is true. I want to be able to calculate, for example, the resistivity of a 1 centimeter length of 'metallic' carbon nanotube. I would find even a 1% accuracy to be quite acceptable. Jamesdbell8 (talk) 01:39, 26 July 2012 (UTC)

There are two contributions to the resistance of a nanotube. The first is the contact resistance. This itself has two components, the first being the intrinsic contact resistance that arises from going from a 3D system (the leads) to a 1D system (the nanotube) and back to 3D. This results in a resistance of 1/(2G₀), or about 6.4 kOhms. There can also be extra contact resistance (in many cases much larger than 6.4 kOhms) from an imperfect interface between the metal leads and the nanotube. The second contribution is the internal resistance. This arises from electrons scattering inside the nanotube, e.g. with defects on the surface or with phonons. At low temperature (~4 K), where phonons are frozen out, the impurity-dominated internal resistance can be as low as ~1 kOhm per micron of length (see e.g. this paper). Note that there is nothing "fundamental" about this number; it is an empirical observation. At room temperature, phonon scattering yields an internal resistance ~10 kOhms per micron. So a cm length metallic nanotube would have a resistance of > 1 MOhm, and possibly much higher. Tls60 (talk) 17:53, 26 July 2012 (UTC)

ArbCom elections are now open!

Hi,
You appear to be eligible to vote in the current Arbitration Committee election. The Arbitration Committee is the panel of editors responsible for conducting the Wikipedia arbitration process. It has the authority to enact binding solutions for disputes between editors, primarily related to serious behavioural issues that the community has been unable to resolve. This includes the ability to impose site bans, topic bans, editing restrictions, and other measures needed to maintain our editing environment. The arbitration policy describes the Committee's roles and responsibilities in greater detail. If you wish to participate, you are welcome to review the candidates' statements and submit your choices on the voting page.
