Charge carriers in semiconductors

edit

There is a fundemental mistake in the description FET and BJT operation. FETs are not "complex" devices, they are mjority carrier transistors. It is the BJTs that rely on minority carrier injection into the base. The two seem to have been confused. I will correct it but would like more discussion.--Murat (talk) 19:17, 22 November 2009 (UTC) - copied from Talk:Charge carriers in semiconductors, content merged into this article.

Recent edits mention electrons in n-type materials and holes in p-type materials, but ignores minority carriers (in BJTs) and inversion layers (in FETs). Gah4 (talk) 13:18, 5 November 2020 (UTC)Reply

This article is WRONG

edit

I have seen many examples of all of the gauge bosons being called charge carriers (as a synonym for exchange particle/quanta). Exclusion of all but the electromagnetic force, as well as totally ignoring the difference between gauge field quantum physics and simple electromagnetics is just sloppy. Can someone write a clarification that there are indeed two usages for the term?173.189.74.194 (talk) 12:25, 13 June 2013 (UTC)Reply

If there needs to be discussion of gauge bosons and such, they should have their own article. Or maybe they should be discussed more in charged particle. This is for the solid-state physics version of charge carrier. Gah4 (talk) 23:52, 27 June 2020 (UTC)Reply

I wonder about that. The solid-state physics presentation at Electrical resistivity and conductivity: Conductivity and current carriers doesn't distinguish between negative ions and electrons or between positive ions and holes. This article does. —Hoziron (talk) 16:16, 16 July 2020 (UTC)Reply

Metals

edit

The article says: In metals, the charge carriers are electrons which ignores the possibility of hole bands in metals. Consider that most power lines are aluminum, and that aluminum has conduction in both electron and hole bands, a large fraction of our power is conducted by holes.

FETs

edit

FETs are named for p-channel or n-channel. In depletion mode devices, that will match the type of the semiconductor. In enhancement mode, it is an inversion layer, and so effectively the opposite type of the channel region, but they are still majority carriers. Gah4 (talk) 20:31, 17 February 2019 (UTC)Reply

It seems that there is supposed to be a merge discussion, but I don't see one. Maybe I need to start it. Gah4 (talk) 23:50, 27 June 2020 (UTC)Reply

  • Oppose: charge carrier mostly discusses the group (collective) motion of charges in a metal or semiconductor, where charged particle discusses individual particles, many of which are not part of solid-state physics. While effective mass is important here, again, it is considered in the context of collective motion. On the other hand, it does seem that charged particle could use some work, especially to make it longer. Gah4 (talk) 23:50, 27 June 2020 (UTC)Reply

Charged particles=elementary charged particles. Charge carriers=collective behavior in solid state. These two articles should not be merged. Ponor (talk) 12:40, 28 June 2020 (UTC)Reply

  • Those two are fundamentally different concepts. Charged particles are subject of atomic and molecular physics, nuclear physics, and particle physics; such particles are actually particles. This article is a subject of solid state physics. A charge carrier is not always a particle, a solid state concept called as hole also can be considered as a particle-like concept or a pseudo-particle in a metaphoric manner. Also there is some other particle-like approach in solid state physics, called phonon. A phonon is a so-called particle of sound. Those are not same as the generally known particles as covered in aforementioned areas of physics. So, physicist in the solid state physics say that "let's consider those are particle or "let's consider the previous spot of the electron as hole, it moves and takes the place of the some other electron". --Evolutionoftheuniverse (talk) 02:20, 6 July 2020 (UTC)Reply
