What type of semiconductor is formed by adding trivalent impurities? (2023)
Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about impurities. Impurities are substances added to a semiconductor to change its properties.
Step 3: Know what trivalent impurities are. Trivalent impurities have three valence electrons. An example is boron.
Step 4: Add trivalent impurities to the semiconductor. When you add boron to a semiconductor like silicon, it creates 'holes' where electrons can move.
Step 5: Understand what 'holes' are. Holes are the absence of electrons and can carry positive charge.
Step 6: Conclude that adding trivalent impurities creates a p-type semiconductor. This type of semiconductor has more holes than electrons.
