A silicon (Si) sample is doped with 108 Boron (B) atoms/cm at temperature 300 K. Answer the following questions. (a) What is the equilibrium electron concentration, no at 300 K? (2 marks) (b) Where is E, relative to E, for temperature of 300 K? Calculate and comment on the result. (5 marks) (c) Determine the conductivity, o(-cm') at same temperature. (2 marks) (d) Sketch and label the resulting energy band diagrams for the sample. (4 marks) (e) What happen to the result of E, above if the temperature has been increased from 300 K to 600 K? Discuss on the difference. (7 marks) T
