Define the following terms as they pertain to semiconducting materials: intrinsic, extrinsic, compound, clemental. Now provide an example of each.

Question: Define the four terms related to semiconducting materials and provide an example for each. Answer: 1. Intrinsic semiconducting materials are pure materials with no intentional impurities. They have equal numbers of electrons and holes. Example: Pure silicon (Si) or germanium (Ge). 2. Extrinsic semiconducting materials are obtained by adding impurities to intrinsic materials, resulting in an unequal number of electrons and holes. Example: Silicon doped with phosphorus (n-type) or silicon doped with boron (p-type). 3. Compound semiconducting materials are made up of two or more elements from different groups in the periodic table. Example: Gallium arsenide (GaAs) or cadmium sulfide (CdS). 4. Elemental semiconducting materials are composed of only one type of element. Example: Pure silicon (Si) or germanium (Ge).
