2011 · Q142

NEETPhysicsSemiconductor ElectronicsMCQ+4 / −1
If a small amount of antimony is added to germanium crystal
  1. A
    it becomes a p-type semiconductor
  2. B
    the antimony becomes an acceptor atom
  3. C
    there will be more free electrons than holes in the semiconductor
  4. D
    its resistance is increased
View written solutionFree

Correct answer: C

If a small amount of antimony is added to germanium crystal, crystal becomes n-type semiconductor. Hence, there will be more free electrons than holes.
