SOLVED: 3. Consider an n-type GaAs sample doped with 1012 cm-3 Si atoms (dopant binding energy of 30 meV). a) Explain where the Fermi level is located at T = 0 K. (Hint: consider all energy levels occupied by electrons and remember the definition of Fermi level) b) Calculate the position of Fermi level at T = 300 K with respect to Ei. (Assume full donor ionization) c) Calculate the position of Fermi level at T = 700 K with respect to Ei. d) Sketch the energy band diagram with the donor level and
