Study Notes
Semiconductor Conductivity
- Semiconductors have conductivity between conductors and insulators.
- They act as insulators at low temperatures and as conductors at high temperatures.
Common Semiconductor Material
- Silicon (Si) is a common semiconductor material.
Impurity Role in Semiconductors
- Impurities are added to semiconductors through doping to alter their conductivity.
- N-type semiconductors are created by doping with impurities that add extra electrons.
- P-type semiconductors are created by doping with impurities that create electron holes.
Semiconductor Component Usage
- Transistors are electronic components that use semiconductors.
- Integrated circuits (ICs), which are commonly referred to as microchips, are made of semiconductors.
Temperature Variation Impact
- Higher temperatures increase conductivity in semiconductors.
- Lower temperatures decrease conductivity in semiconductors.
