MCQ
Which one of the following statement is false:
  • A
    Work is a state finction.
  • B
    Temperature is a state function.
  • C
    Change in the state is completely defined when the initial and final states are specified.
  • D
    Work appears at the boundary of the system.
✓

Answer

  1. Work is a state finction.

Explanation:

Majority carrier in a n − type semiconductor are holes. This statement is false.

Since, in n−type semiconductor, the pentavalent impurity atoms donate electrons o the host crystal and the semiconductor doped with donars (pentavalent impurity) is called n − type semiconductor.

Therefore majority carrier in a n−type semiconductor are electrons.
