Unformatted text preview: l) at thermal equilibrium is given by the relation E EF E EA N D : N 0 : N A exp D : 1 : exp F kT kT (a) Sketch the densities of these three species as the Fermi level moves from EV to EC. Which species dominates in heavily doped p‐type material? In n‐type material? (b) What is the effect of the defects on the majority‐carrier concentrations? (c) Using the above information, determine the charge state of the defect levels and the position of the Fermi level in a silicon crystal containing no shallow dopant atoms....
