Questions & Step-by-Step Solutions
Which of the following materials is commonly used as a p-type semiconductor?
Correct Answer: Boron-doped Silicon
Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about p-type semiconductors. P-type semiconductors are materials that have 'holes' which allow for the flow of electricity.
Step 3: Know what 'doping' means. Doping is the process of adding impurities to a semiconductor to change its electrical properties.
Step 4: Identify common dopants for p-type semiconductors. Boron is a common dopant used to create p-type semiconductors.
Step 5: Understand how boron affects silicon. When boron is added to silicon, it creates holes in the silicon lattice, allowing it to conduct electricity as a p-type semiconductor.
