SUMMARY

The discussion focuses on the derivation of a specific equation related to solid state physics, particularly concerning the behavior of electrons and holes in semiconductors. Key symbols include n0 for the number of electrons, p0 for the number of holes, NA for positive acceptor ions, and ND for negative donor ions. The relationship ni=pi=n0=p0 is highlighted for intrinsic semiconductors. Participants recommend researching "carriers doped semiconductor" for comprehensive derivations, with a specific resource provided from the University of Colorado.

PREREQUISITES
  • Understanding of solid state physics concepts
  • Familiarity with semiconductor physics
  • Knowledge of electron and hole dynamics in semiconductors
  • Basic grasp of density of states in materials
NEXT STEPS
  • Research "carriers doped semiconductor" for derivations and explanations
  • Study the density of states in semiconductors
  • Explore the role of acceptor and donor ions in semiconductor behavior
  • Review intrinsic vs. extrinsic semiconductor properties
USEFUL FOR

Students and professionals in solid state physics, semiconductor researchers, and anyone looking to deepen their understanding of semiconductor behavior and equations.

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.
