p-n junction
Definition: In electronics, a p-n junction is the interface between a p-type semiconductor and an n-type semiconductor, which is created by doping different impurities in the material. It forms a basic building block for various electronic components like diodes, transistors, and solar cells.
Senses/Usages:
- Diode:
- Part of Speech: Noun
- Sense: A diode is a two-terminal electronic component that allows the flow of electric current in one direction while blocking the current in the opposite direction. It functions based on the p-n junction principle.
- Example Sentence: The p-n junction in the diode prevents the current from flowing in the reverse direction.
- Transistor:
- Part of Speech: Noun
- Sense: A transistor is a three-terminal electronic device that amplifies or switches electronic signals and electrical power. It consists of two p-n junctions and plays a crucial role in modern electronics.
- Example Sentence: The p-n junctions in the transistor are responsible for controlling the flow of current across the device.
- Solar Cells:
- Part of Speech: Noun
- Sense: Solar cells, also known as photovoltaic cells, are devices that convert sunlight directly into electrical energy. These cells rely on the p-n junction to facilitate the generation of electricity from solar power.
- Example Sentence: The p-n junction within the solar cell converts solar energy into usable electrical energy.
