Question

If the lattice constant of this semiconductor is decreased, then which of the following is correct?

  1. All E subscript c end subscript comma E subscript g comma end subscript comma E subscript x end subscript increase    
  2. E subscript C end subscript and E subscript v end subscript increase, but E subscript g end subscript decreases    
  3. E subscript c end subscript and E v decrease, but Eg increases    
  4. All E subscript C end subscript comma E subscript g end subscript comma E v decrease    

The correct answer is: E subscript c end subscript and E v decrease, but Eg increases


    If lattice constant of semiconductor is decreased, then EC and Ev decrease but Eg increases.
