Germanium is an example of

Options

A. intrinsidc semiconductor
B. n-type semiconductor
C. p-type semiconductor
D. insulator.

Answer

**Step-by-Step Solution:**

1. **Understanding the Term 'Germanium':**
- Germanium is a chemical element with the symbol Ge and atomic number 32. It is a metalloid that has properties of both metals and non-metals.

2. **Identifying the Types of Semiconductors:**
- Semiconductors can be classified into different categories based on their purity and the type of doping they undergo:
- **Intrinsic Semiconductor:** A pure semiconductor without any significant impurities.
- **N-type Semiconductor:** A semiconductor that has been doped with pentavalent impurities (elements with five valence electrons).
- **P-type Semiconductor:** A semiconductor that has been doped with trivalent impurities (elements with three valence electrons).
- **Insulator:** A material that does not conduct electricity.

3. **Determining the Classification of Germanium:**
- Germanium, in its pure form, is considered an intrinsic semiconductor because it does not contain significant amounts of dopants. It can conduct electricity under certain conditions, but it is not doped with any impurities that would classify it as either N-type or P-type.

4. **Conclusion:**
- Based on the definitions and characteristics of the types of semiconductors, we can conclude that germanium is an example of an **intrinsic semiconductor**.

**Final Answer:** Germanium is an example of an **intrinsic semiconductor**.
