Question

As the doping to a pure semiconductor increases, the bulk resistance of the semiconductor

• A. Remains the same
• B. Increases
• C. Decreases
• D. None of the above

Answer 1

The correct option is C Decreases

Doping is the process of adding impurities to a semiconductor. Depending on the impurity, either free electrons or holes are created as charge carriers. These carriers enhance the conductance of the material. By adding more impurity, more charge carriers are created which further increase the conductance and decrease resistance.
