I think the article needs to be re-arranged. The paragraph slapped on at the end is very non-encyclopedia in its tone. A much better approach would be to write it out in sections with original derivation and issues or something like that. Grj23 (talk) 07:12, 29 October 2009 (UTC)Reply

I would say that the last section should be expanded and reference more than one paper. Commonly current literature tends to use the form

${\displaystyle \rho (T)=\rho _{0}\exp(T_{0}/T)^{\beta }}$.

This would allow for the article to include different types of variable-range hopping, which effect the value of ${\displaystyle \textstyle \beta }$. Also, the in-line Latex typesetting needs to be improved. --Obvious Alias (talk) 18:10, 28 June 2013 (UTC)Reply

The general equation for this should be σ = σ_o e^(-(To/T)^(1/p)) Where p = (1 + n)/(1 + n + d) and d = dimensionality?

Also I found it odd that under Variable-Range hopping Efros and Shklovskii's model is not mentioned.

Mott would predict p = 1/4 while Efros would predict p = 1/2. Nearest Neighbor would be p = 1
