I have been studying the Boltztrap2 software to calculate the thermoelectric properties of materials. However when following the tutorial given, the Seebeck coefficient is plotted against
mu as seen here under section 5 towards the bottom of the page.
However as far as I have seen (being a newbie), the symbol
mu is used for both
mobility as well as
chemical potential. Is there a way to distinguish between the two?
Also, why is the graph plotted with
mu-fermi energy? Does this give some advantage when visualizing the data? If I am working with an non-doped semiconductor, should I consider the Seebeck coefficient value at
mu-fermi energy = 0? Should I be considering this
mu-fermi energy axis as an indication of the doping level in the first place?
