Questions & Step-by-Step Solutions

Which type of semiconductor has an excess of electrons?
  • Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
  • Step 2: Learn about the two types of semiconductors: N-type and P-type.
  • Step 3: Know that N-type semiconductors have extra electrons. This means they have more negatively charged particles than normal.
  • Step 4: Realize that these extra electrons come from adding special materials called donor impurities to the semiconductor.
  • Step 5: Conclude that N-type semiconductors are the ones with an excess of electrons.
