What is the fraction of the electron states occupied by, Ask an Expert

Academics

What is the fraction of the electron states occupied by electrons at an energy of E-E_F+0.0455eV at T=300K? Use the very accurate value of the Boltzmann constant.

What is the fraction of these states occupied by holes (or empty of electrons)?

What are the electron and hole occupancy fractions if the Boltzmann approximation is made and what are the percentage errors? Explain why one error is negligible while the other is significant?
