Which of the following is a p-type semiconductor? (2020)
Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about types of semiconductors. There are two main types: n-type and p-type.
Step 3: Know what p-type means. A p-type semiconductor has 'holes' that allow electricity to flow. These holes are created by adding certain elements.
Step 4: Identify trivalent elements. Trivalent elements have three valence electrons. When added to silicon (which has four valence electrons), they create holes.
Step 5: Recognize that boron is a trivalent element. When boron is added to silicon, it creates holes, making it a p-type semiconductor.
Step 6: Conclude that boron is the answer to the question about which is a p-type semiconductor.
