6) Briefly answers the following questions using the plot below: Log([V]/[VO]) 4 4 -6 +1 V E Fermi energy E a) If the material is doped n+ (Fermi level at CB edge), what will be the majority charge state of the vacancies [3pt]? b) If the material is doped p+ (Fermi level at VB edge), and the total density of vacancies is 1*107 cm, determine the density of V+ vancancies and the density of neutral vancancies Vo hint: they should add up to the total! [4pt]. c) If the material is intrinsic, explain if you expect to see Traps or Recombination centers & why. [4]
