Study Notes
Classification of Materials
- Materials are classified into three categories: conductors, insulators, and semiconductors based on their electric conductivity.
- This classification is dependent on the number of free electrons available within the materials, excluding bonded orbital electrons.
Conductors
- Metals like copper and gold are good conductors.
Insulators
- Materials like glass and plastics are very bad conductors.
Semiconductors
- Semiconducting materials like germanium and silicon have conductivity between good conductors and insulators.
- Charges movement in semiconductors can be manipulated to create electronic devices.
- Silicon and germanium are used as base materials for making electronic components like diodes, transistors, etc.
- Silicon and Germanium are elemental semiconductors.
Elemental Semiconductors
- Silicon has 14 electrons.
- Germanium has 32 electrons.
