Explain how the intrinsic carrier concentration of a semiconductor is created and why the intrinsic carrier concentration of Si is lower than that of Ge. The band gap energies of Si and Ge at 300 K are 1.1 eV and 0.67 eV, respectively. The Si sample is doped with 1015 cm³ phosphorus atoms. Find the electron and hole carrier concentrations of the doped semiconductor.
