Calculate intrinsic carrier concentrations in Ge at temperatures 293 K (room temperature). J73 K (boiling point of water), and 253 K (wittier in Minnesota). Compare the results and formulate conclusions about the temperature dependence of carrier concentrations in this temperature range. In your calculations, assume that the effective masses of electrons and holes in Ge coincide with the electron mass at rest. The band gap in tie is 0.67 eV.
