	A vague discomfort at the thought of the chemical potential is still characteristic of a physics education. This intellectual gap is due to the obscurity of the writings of J. Willard Gibbs who discovered and understood the matter 100 years ago.

The Chemical Potential


	This module is registered in the "basic" part of the Semiconductor course, beause the chemical potential belongs to basic thermodynamics. However, people with a mostly physics background (like me) may often have learned exciting things like Bose-Einstein condensations and the Liouville theorem in their thermodynamics courses, but not overly much about chemical potentials and, most importantly, chemical equilibrium .
	If you want to refresh your memory, the following link will take you to the hyperscript "Defects in Crystals" which contains a detailed discussion of the chemical potential in its "Advanced" part.
