Copied from talk page of Valence band
The two articles are rather short and contain significant overlap (one cannot be understood without the other). Some materials, such as semiconductors, feature both in tandem (movement of electrons in conduction band, movement of holes in valence band). As such, I propose that the two articles be merged into an article titled "Valence and conduction bands" which not only discusses the two bands individually, but also the commonalities between the two and how they can work in tandem. A potential extension of such an article would include the different types of conduction valence band combinations (metal, semimetal, semiconductor, etc). Would like to cite the unified page HOMO/LUMO as precedent.-- Officer781 ( talk) 11:05, 25 May 2015 (UTC)
I got to this page through a link from electric current, though I am not so sure about the reasoning behind that link. In the introduction of this article, it indicates that in metals, a (implied one) band is partially filled. In many metals, bands overlap such that more than one are partially filled. Even more, when that happens, often one is more than half full, in which case the charge carriers are holes. Aluminum, the metal used for most power lines, has both hole and electron bands, and at high magnetic fields, a positive Hall coefficient. The electric current page could have ignored band structure, but instead mentioned charge carriers as electrons in a conduction band. Gah4 ( talk) 21:29, 10 May 2017 (UTC)
Is this where we should explain impurity band conduction in silicon ? and is " blocked impurity band conduction" a thing ? (Used in Spitzer Space Telescope and JWST). Band_diagram#Energy_levels briefly mentions EImp. - Rod57 ( talk) 12:41, 27 December 2021 (UTC)

Should somewhere, maybe here, explain indirect gap, and especially that some can have a negative indirect gap? Gah4 ( talk) 05:54, 16 February 2022 (UTC)
