1. Consider a Silicon sample with Na=10^19 cm^-3 a. Compute the electron and hole concentrations [5 points] b. Compute the fermi level position relative to Ec or Ev at T=300

K. Will the fermi level change if we increase the temperature to 600 K?Explain if it will change and why by writing down all the equation you will need to find new fermi level position at 600 k. No need to compute anything for 600 k. Just provide equations and steps.(10+5 points].
