Conductivity and Resistivity Ranges

The source opens Semiconductor with ranges for metals, semiconductors, and insulators.

Material	Resistivity	Conductivity
Metals	$10^{-2}$ - $10^{-6}$	$10^2$ - $10^8$
Semiconductors	$10^{-5}$ - $10^{-6}$	$10^5$ - $10^{-6}$
Insulators	$10^{11}$ - $10^{19}$	$10^{-11}$ - $10^{-19}$

Variables & Notation

$\rho$

density or resistivity depending on context

$\sigma$
