Question: In a semiconductor, what is the effect of doping?

Options:

  1. It increases the number of free electrons.
  2. It decreases the conductivity.
  3. It makes the material more insulating.
  4. It has no effect on the material.

Correct Answer: It increases the number of free electrons.

Solution: 

Doping a semiconductor introduces impurities that increase the number of free charge carriers, enhancing its electrical conductivity.

Questions & Step-by-Step Solutions

In a semiconductor, what is the effect of doping?
  • Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions, but not as well as a conductor like copper.
  • Step 2: Learn about doping. Doping is the process of adding small amounts of impurities to a semiconductor.
  • Step 3: Know the types of dopants. There are two main types of dopants: n-type (which adds extra electrons) and p-type (which creates 'holes' or missing electrons).
  • Step 4: See how doping affects charge carriers. Doping increases the number of free charge carriers (electrons or holes) in the semiconductor.
  • Step 5: Understand the result of doping. With more charge carriers, the semiconductor can conduct electricity better, which means its electrical conductivity is enhanced.
  • Doping in Semiconductors – Doping involves adding impurities to a semiconductor to modify its electrical properties, specifically to increase the number of free charge carriers (electrons or holes).
