Reading Review Notes for Week 11:

• Re-read the notes from last class. 

-What is N_C, N_V, and n_i?

-Where is E_F in an intrinsic semiconductor?

• Things to think about

-Why are the values of the bandgaps for Si, GaAs, and Ge different?

• Read sections 5.2

 -What is binding energy?

-What does the approximation in Eq. 5.16 assume?

-Why is there a 1/2 term in Eq. 5.17?

-Explain what compensation doping is.

*(Apply your knowledge) Study example 5.5.  Generate a plot of how Fermi level changes with dopants.

*(Apply your knowledge) Plot how the band structure changes for an applied voltage to a p-type semiconductor.

• Important terms you should know

  -p-type

  -acceptor

  -n-type

  -donor

  -compensation
