The correct Answer is:
To determine which element silicon should be doped with to create a p-type semiconductor, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Types of Semiconductors**: - There are two types of semiconductors: p-type and n-type. - P-type semiconductors are created when silicon is doped with elements that have fewer valence electrons than silicon (which has 4 valence electrons). This creates "holes" in the crystal lattice, which can carry positive charge. 2. **Identify the Group of Elements**: - Silicon (Si) belongs to Group 14 of the periodic table. - To create a p-type semiconductor, we need to dope silicon with elements from Group 13, which have 3 valence electrons. 3. **Choose the Correct Dopant**: - Common Group 13 elements that can be used to dope silicon include boron (B), aluminum (Al), gallium (Ga), and indium (In). - These elements will create holes in the silicon lattice when substituted for silicon atoms. 4. **Analyze the Options**: - If the options include elements like arsenic (As), phosphorus (P), or antimony (Sb), these belong to Group 15 and would create n-type semiconductors instead, as they have 5 valence electrons and contribute extra electrons rather than holes. 5. **Conclusion**: - The best choice for doping silicon to create a p-type semiconductor is boron (B), as it is a Group 13 element. ### Final Answer: Silicon should be doped with **boron (B)** to give a p-type semiconductor.
