Study Notes
Semiconductors Overview
- Semiconductors are materials with electrical conductivity between that of conductors and insulators.
- They are essential in electronic devices, functioning as the building blocks for components like diodes and transistors.
Types of Semiconductors
- Intrinsic Semiconductors: Pure materials with no impurities; examples include pure Silicon and Germanium.
- Extrinsic Semiconductors: Doped materials that have been altered with impurities to enhance conductivity.
Key Properties and Measurements
- The conductivity of Germanium at room temperature is approximately 0.47 S/m.
- Silicon has a forbidden energy gap of around 1.1 eV, which is crucial for its electronic properties.
- The forbidden energy gap for Germanium is about 0.66 eV.
- The conductivity of Silicon at room temperature is roughly 1.5 S/m.
Diodes and Their Functionality
- The main property of a diode is its ability to allow current to flow in one direction while blocking it in the opposite direction, serving as a rectifier in circuits.
Identifying Types of Semiconductors
- An example of an intrinsic semiconductor is pure Silicon.
- Common types of semiconductors include both intrinsic and extrinsic, while certain materials like insulators (not classified as conductors of electricity) are NOT types of semiconductors.
