But in metals the electron-electron interaction is very small because of the pauli principle. that's explained in the book of Ibach and Lüth "Solid state physics". there's written that you can neglect that effect and can treat the electrons as non-interacting particles. so in my opinion the...

Hi there, i've got a question about the mobility of the electrons in semiconductors and metalls. in a semiconductor the mobilities are ~ 1000 cm²/Vs. In metals the mobilities are in the range of 50 cm²/Vs. what's the origin of that great difference?

Ok, thanks. So by defining \mu(N) with that approximation for the derivative, it makes sense to me, that the chemical potential lies inside the band gap at T=0 K. But now the next question is, what happens at a temperature where there are some electrons inside the conduction band? the chemical...

Hi there, i've already read some topics in this forum about the fermi-energy/chemical potential. I've also read the article "The chemical potential of an ideal intrinsic semiconductor" from Mark R. A. Shegelski which made the whole thing a little bit more clear to me. but there are some...
