Thermodynamics in Earth and Planetary Sciences by Jibamitra Ganguly, p. 240. This text uses "internal", "external", and "total chemical potential" as in this article.
Electrochemistry at Metal and Semiconductor Electrodes, by Norio Sato, pages 4–5.
Physics Of Transition Metal Oxides, by Sadamichi Maekawa, p. 323.
The Physics of Solids: Essentials and Beyond, by Eleftherios N. Economou, page 140. In this text, total chemical potential is usually called "electrochemical potential", but sometimes just "chemical potential". The internal chemical potential is referred to by the unwieldy phrase "chemical potential in the absence of the [electric] field".
