Comment on "Spin-Gradient-Driven Light Amplification in a Quantum Plasma"
... the other hand, when T ≫ TF and Maxwell-Boltzmann statistics apply, quantum spin effects are negligible, being a small perturbation [of O(µB B/T ) ≪ 1] to the standard Vlasov kinetics (as also stated in [2]). At high temperatures, Larmor moments µL = T /B dominate over spin moments (µL ≫ µB ). Also, ...

... One way of understanding how hole number density outnumbers electron number density (as is the case for p-type material) is that since aluminium atoms have only 3 valence electrons to form covalent bonds with 4 neighbouring silicon atoms, there will be a missing electron in one of the 4 covalent bon ...
