If in GaAs, the Fermi level is 0.30 eV below the conduction band. [10] calculate the thermal equilibrium electron and hole concentration at room temperature. Bandgap of CaAs is 1.42 eV, the effective density of states of the conduction band at 300K is 4.7x10 cm and the effective density of states of the valence band is 7x10¹ cm³.
