Discussion Overview

The discussion centers around the derivation of a specific equation related to solid state physics, particularly in the context of semiconductors. Participants seek to clarify the equation's components and potential derivation methods.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • The original poster (OP) requests help with the derivation of an equation they encountered in class materials.
  • One participant identifies the course as solid state physics and explains the meaning of various symbols used in the equation, such as n0, p0, NA, and ND.
  • Another participant suggests starting with the concept of density of states as a possible approach to derive the equation.
  • A different participant mentions that a simple Google search for "carriers doped semiconductor" yields numerous resources that provide derivations, indicating that the information is readily available online.
  • A final post notes that the thread is old and advises against reviving it, leading to the closure of the discussion.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the derivation itself, but there is agreement on the context of the equation and its relevance to solid state physics. The discussion remains unresolved regarding the specific derivation process.

Contextual Notes

The discussion lacks detailed assumptions about the derivation process and does not provide specific mathematical steps or definitions beyond those mentioned in the posts.

Equation in pink:

I was absent so I was going through the slides and I saw that equation. There isn't a derivation shown. Do you guys have any ideas?

What course is this?

What do the symbols mean?

This is for solid state physics.

n0 represents the number of electrons in a semiconductor. p0 represents the number of holes in a semi conductor.

NA represents the number of positive (acceptor) ions. ND represents the number of negative (donor) ions.

ni=pi=n0=p0 in an instrinsic semiconductor.
 
Maybe you could start with the density of states.
 
If you Google "carriers doped semiconductor", 7 out of the top 7 results will lead you to a derivation. I stopped counting at that point. :biggrin: http://ecee.colorado.edu/~bart/book/extrinsi.htm is the first.
 
This thread is from 2013, and the OP has not been here for more than 2 years. Please do not revive old threads like this.

Thread closed.
