An n-type semiconductor is
Text Solution
Verified by ExpertsThe correct answer is:
C
An n-type semiconductor is formed by doping a pure semiconductor ( Si or Ge ) with a pentavalent impurity (e.g., P, As, Sb).
• The impurity atoms donate extra electrons, increasing the number of free electrons.
• However, the number of positive charges (protons) and negative charges (electrons) remains equal overall.
Therefore, an n-type semiconductor is electrically neutral, not negatively charged.
