What physical process determines the property of photon entanglement in a SPE?

For instance, both nitride NW-QDs and h-BN point defect based SPEs seem to exhibit photon entanglement. Which platform will provide stronger entanglement? I suspect, that purity of the single...

We know Fp = Ei – kT ln(p/ni). But how could we relate quasi fermi level with the equilibrium fermi level like Fp (xn) = Efn –kT ln (pn (xn)/ pno)?

Fp (xn) = EFn –kT ln (pn (xn)/ pno). where EFn is the equilibrium Fermi level of the n-side of the junction.
