a) Sketch the band diagram for Si doped with P at T > 0 K.
b) Label the conduction and valence bands, and also Ec, Ev, Eg, and the donor and acceptor levels, as applicable.
c) State the numerical values for Eg, Ec - Ed or Ea - Ev, as applicable.
d) Indicate if the semiconductor is p-type or n-type and identify the majority carriers as applicable.
