i think this article is only a stub, so i put the tag on the test.

Many information is absent.

Equation Error:

∂Q = (nAv)q is surely not correct. The right-hand side is equal to the current, not the change in Q. Either the LHS should read "I" or the RHS should include "dt" in the numerator. -- Anonymous

[edit] More changes are desirable

I just made some cosmetic changes now, but more changes are necessary. Probably rho for charge density is confusing in a context where rho is commonly used for specific resistivity. The article is also incomplete. I would have expected a relation with the relaxation time tau here. /Pieter Kuiper 11:44, 20 September 2007 (UTC)

[edit] Electron velocity

I just redirected this term to here, as they are essentially the same aren't they? The text of the article is below.

{{Unreferenced|date=February 2007}}

Electron velocity is a very important value in computing. Electron is the subatomic particle responsible for electromagnetic field, that's the way to transmit information in electronic hardware. In a metallic atom the electrons on his orbit are relatively free to move from an atom to one other; this movement is cause of current, which is an electron's flow.

According to relativistic model electron in an hydrogen atom would be moving at 2.42 x 10⁸ cm/sec.

For now, the most widely-used material with high electronic velocity is silicon, but faster ones are possible:

1. Gallium arsenide
2. Indium(III) phosphide
3. Indium gallium arsenide
